Author: thompsonbry

Log Message:
-----------
Added a factory pattern for the query engine and hooked it into the unit tests and the sail.
Working in the new logic for named and default graph access paths. I've added a method to clear annotations that we do not want to pass around.
Exposed a method in RuleState (public static) to report the variables to be retained by each join.

Revision: 3705
http://bigdata.svn.sourceforge.net/bigdata/?rev=3705&view=rev
Author: thompsonbry
Date: 2010-09-30 20:23:37 +0000 (Thu, 30 Sep 2010)
Log Message:
-----------
This commit incorporates the named graph decision tree and the various cost models into Rule2BOpUtility. I will do the default graph query patterns tomorrow. The new named graph and default graph logic is not yet enabled when running CI. The cost models have been implemented based on the worksheets. However they are not currently connected to the query planner.
The only remaining features for the quads query branch are:
- PipelineJoin annotation to indicate an empty access path.
- UNION (this is basically a subquery operator).
- Advanced pattern for the ___C indices for default graph queries.
- ISimpleSplitHandler for the SPOC and SOPC shards.
CI is pretty close. The lack of a native UNION operator is responsible for most of the SPARQL query errors that remain. There are also a number of unit tests which have not yet been written for the bigdata operators, which accounts for most of the remaining errors.

Author: thompsonbry
Date: 2010-10-01 20:37:19 +0000 (Fri, 01 Oct 2010)
Log Message:
-----------
Added the ContextAdvancer for default graph access paths. There is a unit test for this. It also tests the StripContextFilter as a side-effect.
Provided coverage for some of the default graph decision tree.

-----------
Worked through more of the default graph access path decision tree. Only the parallel subquery case is left. I've also simplified the decision tree in the worksheet.

Revision: 3767
http://bigdata.svn.sourceforge.net/bigdata/?rev=3767&view=rev
Author: thompsonbry

Log Message:
-----------
Integrated the Sesame TCK with the embedded federation for use in CI validation of the scale-out quads mode query.
This commit also fixes a few places in the query plan generation, including:
- SliceOp wraps the query plan so the top-level operator always runs on the query controller.
- Access path flags set the READONLY bit.
- Cost estimates needed to use the glocal index view (remoteAccessPath=true).
As of now, all but 4 of the tests in the SPARQL test suite are passing against the embedded federation in quads mode. The four tests which are still failing are:
- "Union is not optional".
- "graph-07"
- "graph-11"
- "SELECT DISTINCT *"

-
- - TestJiniFederatedQueryEngine.
-
- - Reconcile IElementFilter, FilterConstructor, and stackable
- striterators for access paths and raw iterators. We should be
- able to use any of the striterator patterns!
-
- There are a lot of partially duplicated classes which need to be
- cleared up. This can be tested on the individual striterator /
- filter and also on the local and remote access paths.
-
- Note: Some filters can be sent with a remote iterator request (for
- example, the advancer), but most are applied after we convert from
- tuples into elements.
-
- IFilterConstructor only works with ITupleIterator.
-
- IElementFilter only filters. It can not resolve, transform, chunk,
- etc. It is currently sent with the iterator to the B+Tree. See
- AccessPath#iterator().
-
- - Break the DistinctSPOIterator into a Distinct(Element)Filter and a
- StripContextFilter.
-
- - AbstractTuple#getObject() should cache the materialized object
- since some patterns used by an AccessPath may request the object
- multiple times. Of course, caching implies that we must clear the
- reference when advancing the iterator. Check TupleFilter and
- friends since there might need to be more than once class which
- caches the object. Clear the reference when the iterator is
- exhausted.
-
- - Adapt the code to use the cost models and decision trees and write
- Unit tests of the default and named graph access path patterns.
-
- - Implement subquery support and subquery operators {Union, Steps,
- Star}. (We can't test Star until we have the mutation API in
- place.)
-
- - PipelineType {Vectored,OneShot}.
-
- A vectored operator processes its inputs in chunks, producing
- output chunks each time it runs.
-
- An one shot operator runs exactly once for a given query and
- must wait for all of its inputs to become available before it
- can begin. For example, SORT is a one shot operator.
-
- - Mutation {Insert, Delete}. Concurrency control. Scale-out
- mutation operators must go through the ConcurrencyManager in order
- to respect the isolation levels imposed within AbstractTask. For
- standalone, we can using either UnisolatedReadWriteIndex or the
- ConcurrencyManager as appropriate (but how can we tell which is
- appropriate!?!).
-
- Note: AccessPath currently does not allow inserts (just
- deletes). Hopefully it can be extended to allow INSERT and UPDATE
- so we can use the same abstraction for mutation operators.
-
- - Mutation {Create, Destroy}. This gets into resource management,
- so defer for the moment but tackle in the context of RDFS closure
- using STAR.
-
- - MemoryType {Chunked,Blocked}.
-
- Blocked operators need to inherit some interface which
- declares annotations for the #of blocks allocated to an
- operator. How those blocks are used is very much operator
- specific. For example, an external merge sort can make
- different use of its buffers than some other kind of
- algorithm.
-
- OneShot operators may be allocated some #of blocks which they
- can use to buffer their inputs. When those blocks are
- exhausted, then they will have to start dumping inputs to the
- disk. However, that is operator specific and not yet defined.

-
-SPARQL named graph query patterns.
-
-Standalone:
-
- Named graph queries use an expander pattern. See
- NamedGraphSolutionExpander.
-
- The following special cases exist:
-
- - The named graph data set is empty (no graphs were identified which
- are known to the database), in which case an empty access path is
- used.
-
- - The named graph data set includes a single graph which is known to
- the database. C is bound and we use the normal access path (this
- is done by special case logic in NamedGraphSolutionExpander and
- should be done by the query rewrite instead).
-
- - The named graph data set includes all graphs. C is left unbound
- and the unmodified access path is used.
-
- - The named graph data set includes more than a threshold number of
- graphs. The context position is left unbound and an IN filter is
- applied to retrict the access path to the desired graphs. See
- NamedGraphsFilteredAccessPath.
-
- FIXME The threshold for this case is 200, which is WAY too
- low.
-
- For standalone the decision should be based on whether more
- leaves would be read (the tuple range count may be used as a
- proxy for this) by issuing individual subqueries for the
- specific as bound predicates or by reading with C unbound.
-
- For scale-out, the decision is different since we can use
- multi-block iterators on the index segments and do fewer
- disk seeks.
-
- - The named graph data set includes more than one graph but less
- than some threshold #of graphs. Parallel subtasks are evaluated
- for each graph in the data set and write on a shared
- BlockingBuffer. See NamedGraphsParallelEvaluationAccessPath.
-
- @todo This is equivelant to an in-memory join, but does not
- scale-out. Replace this with a DataSetJoin rather than the
- expander pattern since that will work for both standalone and
- scale-out.
-
-Scale-out:
-
- As per above, except:
-
- - When the #of named graphs is moderate, the data set graphs are
- joined with the source binding sets (using DataSetJoin) to produce
- a cross product in which each source binding set is replicated for
- each distinct data set graph. Those binding sets are then fed
- into a second join which reads on the access path for the
- appropriate statement index.
-
- - When the #of named graphs is large we need to do something special
- to avoid sending huge graph sets around with the query.
-
-----
-
-SPARQL default graph query patterns.
-
-Note: Default graph queries require us to apply a distinct {s,p,o}
-filter to each default graph access path. The default graph queries
-uses an expander pattern. See DefaultGraphSolutionExpander and its
-inner classes.
-
-The following special cases exist:
-
- - The default graph data set is empty (no graphs were identified
- which are known to the database), in which case an empty access
- path is used.
-
- - The default graph data set includes a single graph which is known
- to the database. C is bound and we impose a filter which strips
- off the context position. Because C takes on only one value, a
- distinct filter is not required. This means that scale-out can
- use normal pipeline joins.
-
- See StripContextAccessPath.
-
- - ___C index: We know that C is strictly ascending in index order
- within each triple. Use an advancer pattern or ignore quads until
- the data changes to a new triple. Apply a filter to strip off the
- context position.
-
- The same optimization works in scale-out using shard-wise pipeline
- joins if the ___C index was created with the constraint that the
- all quads for a given triple are on the same shard.
-
- - SCALEOUT and VERY HIGH VOLUME: Use a distributed external merge
- sort to impose distinct and do operator at a time processing.
-
- - SCAN and FILTER: The default graph data set includes all graphs OR
- the cost of scanning with C unbound is less than the cost of
- subqueries with C bound (for scale-out, subquery cost must be
- estimated for a remote access path). C is left unbound and we
- impose a distinct SPO filter which strips off the context
- position. Unless all graphs are being merged, we also apply an IN
- filter.
-
- SCALEOUT: The join evaluation context is ANY, uses a remote access
- path, and the access path should be configured to move a
- lot of data efficiently over the remote range iterator.
-
- - It is possible to partition the IN filter based on the
- shard on which it will be applied (split the ordered
- list of contexts based on the contexts found in a
- given shard).
-
- See MergeAllGraphsAccessPath.
-
- - SUBQUERY: Parallel subtasks are evaluated for each graph in the
- data set and write on a shared BlockingBuffer. The BlockingBuffer
- is wrapped with an SPORelation.distinctSPOIterator().
-
- SCALEOUT: Mark the join evaluation context as ANY and mark the
- access path as remote.
-
- Tune the capacity for the remote access path iterator.
- When the remote access path will be selective, the
- capacity should be small and we will pay a high price if
- there are a lot of nested subqueries. When the remote
- access path is less selective the capacity should be
- larger to reduce the #of RMI requests made per access
- path.
-
- Note: The way the code is written, the access path will
- do RMI for the range count before issuing the RMI
- iterator request. Look at ways to optimize this.
-
- See DefaultGraphParallelEvaluationAccessPath.
-
-- @todo Lazily create the hash map for the distinctSPOIterator when we
- observe the 2nd distinct SPO value.
-
----
-UNION(ops)[maxParallel(default all)]
-
-Executes each of the operands in the union as subqueries. Each
-subquery is run as a separate RunningQuery but is linked to the parent
-query in which the UNION is being evaluated. The subqueries do not
-receive bindings from the parent and may be executed independently.
-
-Note: In order to avoid materializing all of the intemediate results
-on the query controller, the target for the subqueries SHOULD be
-overriden to be whatever operator is the parent of the UNION.
-
----
-STEPS(ops)[maxParallel(default 1)]
-
-The operands are executed as independent subqueries.
-
-@todo It should be possible to write the results for each step onto a
-named query local resource so they can be reused in subsequent steps.
-
-@todo This operator is really no different from UNION. UNION defaults
-to running all in parallel while STEPS defaults to running them
-sequentially. In addition, there is an assumption for UNION that the
-operands return binding sets and an assumption for STEPS that they are
-mutation operators. However, what makes the UNION work is that the
-operands target the UNION's parent.
-
----
-
-STAR(op) [maxItr(default all)]
-
-Evaluate the operand until its mutation count remains unchanged from
-one round to the next. The operand must write on a resource. The
-fixed point is determined by examining BOPStats.mutationCount.
-
-Do with INSERT/REMOVE since all involve mutation.
-
----
-INSERT(op,pred) : insert elements into an index.
-DELETE(op,pred) : remove elements from an index.
-
-The access path mutation operators construct elements from the source
-binding sets and the asBBound predicates. For each element so
-constructed, they insert/ remove the corresponding element into/from
-the access path. These operators update a mutation counter IFF the
-access path was modified for the constructed element. STAR relies on
-the mutation operator to detect a fixed point.
-
-The mutation access paths need to use the appropriate concurrency
-control to ensure the constraint on the mutable B+Tree is respected.
-This is either the UnisolatedReadWriteIndex or the LockManager /
-ConcurrencyManager.
-
-The basic mutation operators write on an access path and may be
-combined using STEPS in order to update all of the indices associated
-with a relation.
-
- - For incremental TM, we also need to construct an element for the just index
- from the rule and assert it onto that index.
-
- - For the lexicon, we also need to write on the full text index.
-
- - For SIDs mode, we also need to capture the logic to ground the statements by
- binding the SIDs.
-
- - triggers could be integrated here. perhaps events backed by a queue which
- could be either restart safe or query local?
-
-----
-Parallel distributed closure : TBD. Review notes posted on trak.
-
-----
-Lexicon joins -
-
-====
-Features:
-
- - operator-at-once evaluation. The operator is triggered once its possible
- triggers are done. This is just an application of the same utility method
- which we use to decide when a query is done.
-
- - ISimpleSplitHandler to enforce constraint on the SPOC index such
- that an SPO prefix is never split. This has to be IV aware since
- we are now using variable length keys in the statement indices.
-
- - query and connection local resources: creating, destroying and
- using resources. references to query local resources permit reuse
- of intermediate results across different.
-
- CREATE FOO AS TEMP GRAPH ON LOCAL TEMP STORE SPO ONLY SHARED LEXICON
-
- - subquery evaluation (linked parent to child). a subquery may be cancelled
- by a slice without cancelling the parent. cancelling the parent terminates
- all subqueries. whenever a query or subquery is terminated, we need to go
- through its operator and query life cycle tear down methods (unit tests).
-
- - "thick" resources which can be sent along with the query or access either by
- RMI or copied to the node where the query is running on demand. (This could
- be just alternative access path instantiations which are selected by the query
- optimizer or defaulted based on the amount of data to be moved to/from the
- node if not specified.)
-
- - The Predicate could have fromRevision/toRevision annotations which would be
- used for fast computation of the delta between two historical commit points.

- * FIXME Unit tests for non-distinct {@link IElementFilter}s on an
- * {@link IPredicate}, unit tests for distinct element filter on an
- * {@link IPredicate} which is capable of distributed operations. Do not use
- * distinct where not required (SPOC, only one graph, etc).
- * <p>
- * It seems like the right way to approach this is by unifying the stackable CTC
- * striterator pattern with the chunked iterator pattern and passing the query
- * engine (or the bop context) into the iterator construction process (or simply
- * requesting that the query engine construct the iterator stack).
- * <p>
- * In terms of harmonization, it is difficult to say which way would work
- * better. In the short term we could simply allow both and mask the differences
- * in how we construct the filters, but the conversion to/from striterators and
- * chunked iterators seems to waste a bit of effort.
- * <p>
- * The trickiest part of all of this is to allow a distributed filter pattern
- * where the filter gets created on a set of nodes identified by the operator
- * and the elements move among those nodes using the query engine's buffers.
- * <p>
- * To actually implement the distributed distinct filter we need to stack the
- * following:
- *
- * <pre>
- * - ITupleIterator
- * - Resolve ITuple to Element (e.g., SPOC).
- * - Layer on optional IElementFilter associated with the IPredicate.
- * - Layer on SameVariableConstraint iff required (done by AccessPath)
- * - Resolve SPO to SPO, stripping off the context position.
- * - Chunk SPOs (SPO[], IKeyOrder), where the key order is from the access path.
- * - Filter SPO[] using DHT constructed on specified nodes of the cluster.
- * The SPO[] chunks should be packaged into NIO buffers and shipped to those
- * nodes. The results should be shipped back as a bit vectors packaged into
- * a NIO buffers.
- * - Dechunk SPO[] to SPO since that is the current expectation for the filter
- * stack.
- * - The result then gets wrapped as a {@link IChunkedOrderedIterator} by
- * the AccessPath using a {@link ChunkedArrayIterator}.
- * </pre>
- *
- * This stack is a bit complex(!). But it is certainly easy enough to generate
- * the necessary bits programmatically.
- *
- * FIXME Handling the {@link Union} of binding sets. Consider whether the chunk
- * combiner logic from the {@link DistributedJoinTask} could be reused.
- *
- * FIXME INSERT and DELETE which will construct elements using
- * {@link IRelation#newElement(java.util.List, IBindingSet)} from a binding set
- * and then use {@link IMutableRelation#insert(IChunkedOrderedIterator)} and
- * {@link IMutableRelation#delete(IChunkedOrderedIterator)}. For s/o, we first
- * need to move the bits into the right places so it makes sense to unpack the
- * processing of the loop over the elements and move the data around, writing on
- * each index as necessary. There could be eventually consistent approaches to
- * this as well. For justifications we need to update some additional indices,
- * in which case we are stuck going through {@link IRelation} rather than
- * routing data directly or using the {@link IAsynchronousWriteBufferFactory}.
- * For example, we could handle routing and writing in s/o as follows:
- *
- * <pre>
- * INSERT(relation,bindingSets)
- *
- * expands to
- *
- * SEQUENCE(
- * SELECT(s,p,o), // drop bindings that we do not need
- * PARALLEL(
- * INSERT_INDEX(spo), // construct (s,p,o) elements and insert
- * INSERT_INDEX(pos), // construct (p,o,s) elements and insert
- * INSERT_INDEX(osp), // construct (o,s,p) elements and insert
- * ))
- *
- * </pre>
- *
- * The output of the SELECT operator would be automatically mapped against the
- * shards on which the next operators need to write. Since there is a nested
- * PARALLEL operator, the mapping will be against the shards of each of the
- * given indices. (A simpler operator would invoke
- * {@link SPORelation#insert(IChunkedOrderedIterator)}. Handling justifications
- * requires that we also formulate the justification chain from the pattern of
- * variable bindings in the rule).
- *
- * FIXME Handle {@link Program}s. There are three flavors, which should probably
- * be broken into three operators: sequence(ops), set(ops), and closure(op). The
- * 'set' version would be parallelized, or at least have an annotation for
- * parallel evaluation. These things belong in the same broad category as the
- * join graph since they are operators which control the evaluation of other
- * operators (the current pipeline join also has that characteristic which it
- * uses to do the nested index subqueries).
- *
- * FIXME SPARQL to BOP translation
- * <p>
- * The initial pass should translate from {@link IRule} to {@link BOp}s so we
- * can immediately begin running SPARQL queries against the {@link QueryEngine}.
- * A second pass should explore a rules base translation from the openrdf SPARQL
- * operator tree into {@link BOp}s, perhaps using an embedded {@link Prolog}
- * engine. What follows is a partial list of special considerations for that
- * translation:
- * <ul>
- * <li>Distinct can be trivially enforced for default graph queries against the
- * SPOC index.</li>
- * <li>Local distinct should wait until there is more than one tuple from the
- * index since a single tuple does not need to be made distinct using a hash
- * map.</li>
- * <li>Low volume distributed queries should use solution modifiers which
- * evaluate on the query controller node rather than using distributed sort,
- * distinct, slice, or aggregation operators.</li>
- * <li></li>
- * <li></li>
- * <li></li>
- * <li>High volume queries should use special operators (different
- * implementations of joins, use an external merge sort, etc).</li>
- * </ul>
- *
- * FIXME SPARQL Coverage: Add native support for all SPARQL operators. A lot of
- * this can be picked up from Sesame. Some things, such as isIRI() can be done
- * natively against the {@link IV}. Likewise, there is already a set of
- * comparison methods for {@link IV}s which are inlined values. Add support for
- * <ul>
- * <li></li>
- * <li></li>
- * <li></li>
- * <li></li>
- * <li></li>
- * <li></li>
- * </ul>

-------------------------------------------------------------
-
-Some problems:
-
-- Should Appender simply pass the other iterator as m_state to the FilterBase?
-
-- Mapper uses non-Serializable "Method". We should provide defered reflection for the method.
-
-- Merger uses non-Serializable "Iterator".
-
-- Sorter and Resolver should use an annotation pattern so we can create instances from Prolog of the operator. I do not think we can do this when the operator is abstract. Maybe we can have two "Resolver" classes, two "Sorter" classes, etc. The simple one can be used for inline programming. The other one will extend BOpBase and implement IFilter and will be used for query.
-
-- CONTRACTOR should be able to break an iterator into many chunks, not just one. Maybe the API should return an Iterator from an Iterator in which the chunkiness is changed (from element to element[])?
-
-Here is what I have not done yet:
-
-- Striterator unit tests.
-
-- Bop-erator tests.
-
-- MGC: All of the Filterators need to use deferred prefetch. Prefetch
- during the constructor causes problems when we are stacking filters
- using FilterBase. (This is also true for the ITuple filters).
-
-- BT: Write unit tests at the IPredicate/AccessPath level to use
- stackable filters (for the LOCAL and REMOTE access paths). Write
- unit tests for correct range counts with and without local/remote
- filters. Write unit tests for caching of those range counts.
-
-- Write BOp versions for TupleResolver, ...
-
-- done. IPredicate#getConstraint() must go (issues remain with
- BackchainAccessPath).
-
-- The (SPO|Magic)Predicate contructors must be touched up.
-
- - They assume an IElementFilter (IFilterTest). However, the filters
- are now specified with IFilter.
-
- - Those constructor will DROP the local and remote filters unless
- the logic is modified.
-
- - When used remotely, IElementFilter must do ITuple.getObject() and
- MUST be wrapped using ElementFilter to be "Tuple" aware (problem
- with Tuple reference reuse inside the ITupleIterators).
-
- - Reconcile IElementFilter and implementations. IElementFilter was
- transparently wrapped by AccessPath to resolve the ITuple to the
- element before applying the filter. If IElementFilter is used in
- contexts other than the index then all implementations must be
- modified to conditionally resolve the element while filtering.
-
- - IPredicates created from a Relation MUST use the timestamp of that
- relation NOT READ_COMMITTED. Remove the default timestamp
- annotation. Make this required where it is used so we can track
- all of this down.
-
-MikeP:
-
- - BackchainAccessPath. Are the index local or access path filters
- ever used here? If they are then this code needs to be modified.
-
- - The timestamp on which the backchain access path will read MUST be
- passed through to the IPredicate constructors.
-
- - Leave C as an anonymous variable when it will not be used, not
- null.
-
- - Replace NamedGraph and DefaultGraph access paths per the decision
- tree and cost model.
-
- - Set the TIMESTAMP on the predicate.
-
- - Additional SPOPredicate and Predicate constructor cleanup.
-
-Reconcile the com.bigdata.striterators package. Can we get rid of it?
-Incrementally?

Revision: 3770
http://bigdata.svn.sourceforge.net/bigdata/?rev=3770&view=rev
Author: thompsonbry
Date: 2010-10-12 12:05:26 +0000 (Tue, 12 Oct 2010)
Log Message:
-----------
Fix to AbstractSubquery (UNION) to propagate an error thrown by the subquery to the parent query. Added halt(Throwable) to IRunningQuery to support this.
Fixed the last four test failures for scale-out quads query. The problem was that queries which used a UNION were not wrapping the subqueries with an operator which ran on the query controller. I moved the logic to do this from BigdataEvaluationStrategyImpl into Rule2BOpUtility so that it is consistently applied each time we have to wrap a rule (as converted into a bigdata operator tree) with a SliceOp scoped to be evaluated on the query controller.

Revision: 3774
http://bigdata.svn.sourceforge.net/bigdata/?rev=3774&view=rev
Author: thompsonbry
Date: 2010-10-12 17:53:12 +0000 (Tue, 12 Oct 2010)
Log Message:
-----------
Added Serializable to several classes to address RMI errors.
Added wrapper to return a proxy to the MetadataServer to address a Serialization error where the MetadataServer was attempting to return a FutureTask rather than its proxy.
Modified the test harness to allow testing of individual tests per BigdataSparqlTest.

Revision: 3777
http://bigdata.svn.sourceforge.net/bigdata/?rev=3777&view=rev
Author: thompsonbry
Date: 2010-10-12 20:33:07 +0000 (Tue, 12 Oct 2010)
Log Message:
-----------
Fixed problem in BOpBase which was resulting in misreporting of the predicate flags in scale-out.
Moved set of the INLINE property outside of the caching of the properties in BigdataFederationSparqlTest so that its value is now correctly set for each test.
SparqlQueryTest#createRepository() now throws UnsupportedOperationException and must be explicitly overridden.
SparqlQueryTest#upload() no longer turns on autoCommit so we do not have to allow it for the SPARQL test suites.
Modified AccessPath to use ITx.READ_COMMITTED if the timestamp is UNISOLATED and the flags includes READONLY.
Modified AbstractFederation to not report performance counters to the load balancer when the REPORT_DELAY is set to zero.
Changed TERMID_BITS_TO_REVERSE to ZERO (0) in bigdataStandalone.config. This is much more performant for small data sets.
Turned MOVES off in bigdataStandalone.config.

Revision: 3782
http://bigdata.svn.sourceforge.net/bigdata/?rev=3782&view=rev
Author: thompsonbry
Date: 2010-10-13 13:46:30 +0000 (Wed, 13 Oct 2010)
Log Message:
-----------
Fixed test failure on "normalization" by appropriately configuring Unicode collation for that test.
Fixed (or at least worked around) test failures with two data services by not destroying the triple store in tearDown(). tearDown() is somehow being invoked before the query runs to completion which was causing those "no such index" exceptions to be thrown.
Modified the DataServer to use a single proxy for its QueryEngine for its live span. Added support for the proxy of the query engine to the MetadataServer, through we are not yet using query against the MDS.
Simplified the query invocation in BigdataEvaluationStrategyImpl. It now uses QueryEngine.eval/1.
Modified the SAIL to use full read-only transactions when the caller requests a read-only connection. This asserts the appropriate read lock on the transaction server and prevents commit points against which the query is running from being aged out of the RWStore or the federation. (This was not an issue in the SPARQL queries, but it is one of the things that I explored.)
Javadoc changes in FederatedRunningQuery.
Log statement changed in Algorithm_NestedLocatorScan.
Added some logic to dump out the partition locators in AccessPath if the index could not be found. This was eventually traced to the test tear down so the logic is commented out in AccessPath.
Added an explicit getQueryConnection() method to SPARQLQueryTest.
Various changes to the test harness to get things running properly.

-----------
Modified the QueryEngineFactory to use a singleton pattern and modified the BigdataSail to NOT shutdown the QueryEngine when the BigdataSail is shutdown. This fixes a problem where the NanoSparqlServer was creating one QueryEngine per query.

Revision: 3834
http://bigdata.svn.sourceforge.net/bigdata/?rev=3834&view=rev
Author: thompsonbry

Log Message:
-----------
Modified BOpContext to support IMultiSourceAsynchronousIterator so we can attach sources to already running tasks.
Modified BOpContextBase to hold a hard reference to the Executor to avoid problems with errors reported up from the IIndexManager if it has been closed. Since the caller now has access to the Executor after the IIndexManager is closed, the relevant code in RunningQuery now sees a RejectedExecutionException rather than an IllegalStateException.
Modified RunningQuery to attach new chunks to already running tasks, at least in standalone. There is more work that needs to be done here which falls broadly under the category of performance optimizations of the query engine. This optimization is not yet available in scale-out because an RMI is necessary back to the controller and that should not happen in the QueryEngine's run Thread.
There is a known problem with high volume queries, such as LUBM Q9 on U10 or above, that they can block. What appears to be happening is that a join is running into a bounded queue (a BlockingBuffer with a limited capacity). The code needs to be modified either to use an unbounded queue (potentially backed by a direct ByteBuffer), or to emit multiple IChunkMessages (this option was historically used in scale-out), or to chain the consumers and producers together as we did historically in the trunk (this option is very efficient in standalone).
Modified Paths:

Revision: 3836
http://bigdata.svn.sourceforge.net/bigdata/?rev=3836&view=rev
Author: thompsonbry
Date: 2010-10-22 11:59:15 +0000 (Fri, 22 Oct 2010)
Log Message:
-----------
Relocated the IBindingSet implementations and test suites into the com.bigdata.bop.bindingSet package in preparation for developing additional interfaces and classes related to the packaging of arrays of binding sets and large blocks of binding sets for more efficient federated query. I've left IBindingSet in place for the moment as moving it will touch even more files. The com.bigdata.bop.bset package contains operators for copying (and conditional copying) of binding sets. It should probably be renamed to reduce confusion with the package for the binding set implementation classes.
Modified Paths:

* Interface for a set of bindings. The set of variables values is extensible

- * @todo The variable positions in a binding set can be assigned an index by the
- * order in which they are encountered across the predicates when the
- * predicates are considered in execution order. This gives us a dense
- * index in [0:nvars-1]. The index can be into an array. When the bindings
- * are of a primitive type, as they are for the RDF DB, that array can be
- * an array of the primitive type, e.g., long[nvars].
- * <p>
- * This change would require that the singleton factory for a variable was
- * on the {@link Rule} (different rules would have different index
- * assignments), it would require predicates to be cloned into a
- * {@link Rule} so that the variables possessed the necessary index
- * assignment, and that index assignment would have to be late - once the
- * evaluation order was determined, so maybe the Rule is cloned into the
- * {@link RuleState} once we have the evaluation order.
- * <p>
- * There would also need to be a type-specific means for copying bindings
- * from a visited element into a bindingSet if a want to avoid autoboxing.
- * <p>
- * The {@link IConstant} interface might have to disappear for this as
- * well. I am not convinced that it adds much.
- * <p>
- * To obtain a {@link Var} you MUST go to the {@link IVariable} factory on
- * the {@link IRule}. (It is easy to find violators since all vars are
- * currently assigned by a single factory.)
- * <p>
- * Since we sometimes do not have access to the rule that generated the
- * bindings, we would also require the ability to retrieve a binding by
- * the name of the variable (this case arises when the rule is generated
- * dynamically in a manner that is not visible to the consumer of the
- * bindings, e.g., the match rule of the RDF DB).

Revision: 3842
http://bigdata.svn.sourceforge.net/bigdata/?rev=3842&view=rev
Author: thompsonbry

Log Message:
-----------
Modified PipelineJoin to make the predicate an annotation. This is in keeping with a design pattern where operands (other than simple variables and constants) are evaluated in the pipeline and where annotations are interpreted. This also simplifies the RunState logging format.
Modified RunningQuery to track all Futures and permit more than one concurrent operator task per (bopId,shardId). There is now an annotation which controls how many such tasks may run concurrently.
I've also experiment with the parameter space for the BufferAnnotations and the fullyBufferedReadThreshold. These do not appear to have much influence on query performance for either LUBM U50 or BSBM 100M. LUBM query performance remains significantly better in the trunk (13s vs 17s). There is a less significant difference in BSBM performance (4234 vs 4058). Since LUBM U50 tends to be memory based (after the first presentation of each query) this suggests that the performance difference is related more to in-memory dynamics than to disk access. The most significant difference right now between the trunk and the quads query branch is that we chain the input and output buffers of operators together in the trunk but run operators over chunks of materialized inputs in the branch.
Modified Paths:

Revision: 3843
http://bigdata.svn.sourceforge.net/bigdata/?rev=3843&view=rev
Author: thompsonbry
Date: 2010-10-25 15:40:55 +0000 (Mon, 25 Oct 2010)
Log Message:
-----------
accessPathDups were not being detected due to a change in the quads query branch such that hashCode() and equals() for predicates can not be used to test for duplicate patterns of variables and constants. This was fixed by adding the HashedPredicate class. That change cuts significant time from Q2 and Q9.
This change did break 2 of the unit tests in TestQueryEngine and I have not yet diagnosed the problem there. However, the SAIL test suites are all good with this change.
This change also reintroduces query-level logging with breakouts for each join in the pipeline evaluation. This logging level is controlled by QueryLog and corresponds closely to the older RuleStats logging.
At this point, lexicon materialization (Q6,Q14) appears to be slightly slower in the branch, Q2 is faster, and Q9 is slightly slower. The remaining performance difference could be:
- lexicon materialization changes.
- chaining buffers in the trunk but not in the branch.
- buffer configuration properties (explore this again for Q2 and Q9 now that dups are being eliminated).

Revision: 3851

Author: dmacgbr
Date: 2010-11-01 12:32:36 +0000 (Mon, 01 Nov 2010)
Log Message:
-----------
Remove the resource leak, i.e. the thread 'com.bigdata.bop.engine.QueryEngine.engineService1', encountered during unit test runs. The problem is caused by the thread being statically cached in QueryEngineFactory using an instance of IIndexManager as a key. Each test typically has a unique IIndexManager. Code has been added to remove the instance in the '__tearDownUnitTest()' method of BigdataSail. Similar code has been added to a number of individual test classes because a) '__tearDownUnitTest ()' is not public, b) interactions with other tear down code.
