http://bigdata.svn.sourceforge.net/bigdata/?rev=4171&view=rev
Author: thompsonbry
Date: 2011-02-01 20:23:34 +0000 (Tue, 01 Feb 2011)
Log Message:
-----------
This is a branch to address [1], which covers handling of large literals and eliminating the ID2TERM index in favor of direct addressing of URIs and of those literals not amenable to inlining within the statement indices. This is being done within a branch because the change set will involve a change in the physical schema of the lexicon, dropping the ID2TERM index, and changing how the data in the TERM2ID index are represented. By creating the change set in a branch we will be able to evaluate the impact of this change on the storage file size, the IO profile when loading data, and the IO profile and SPARQL performance during query answering.

Author: thompsonbry
Date: 2011-04-11 14:07:20 +0000 (Mon, 11 Apr 2011)
Log Message:
-----------
Creating a branch for the SIDS refactor. This will support reverse lookup from SIDs to Statements. The SID is currently a term identifier. The design will be changed to use a SID IV which directly inlines the representation of the statement as the SID. As a consequence, SIDs will no longer be written into the TERM2ID index.

Log Message:
-----------
Some changes to the stress test to make it compatible with quads mode and to use CAT rather than CAS counters.
This also commits the test to the TERMS branch.

Log Message:
-----------
Per [1], I have taken the HA quorum ZK integration test out of CI since it is not yet supported.
Also per [1], I have made testReallyLongLiteralRoundTrip() silently succeed in the QUADS branch. This will not be fixed in the QUADS branch, but it has already been fixed in the TERMS branch as part of the "large literals refactor".

Revision: 4770
http://bigdata.svn.sourceforge.net/bigdata/?rev=4770&view=rev
Author: thompsonbry

Log Message:
-----------
Removed the SPARQL and BOP plan from the table so we can focus on the performance counters there. Those are now available inline above the table for cross referencing.
Removed several conditional logger tests in the full text search package which were showing up in the profiler. These were all inside of tight loops.

-----------
Modified the full text index search to configure the ConcurrentHashMap with an initial capacity of 256 (it was using an effective value of min(maxRank,10000) which was nearly always 10000 as maxRank defaults to Integer.MAX_VALUE).
Modified the full text index search to configure the ConcurrentHashMap with the exact concurrency level, which is simply the #of distinct tokens in the query document.

Log Message:
-----------
Modified AbstractIV such that the RDF Value cache is sent across the wire for scale-out. See [1] for efficiency concerns relating to when we send the Value cache and what we could do about this. This change has been applied to both the QUADS and the TERMS branches.
See https://sourceforge.net/apps/trac/bigdata/ticket/337 (Compact and efficient movement of binding sets between nodes)

Author: thompsonbry

Log Message:
-----------
Branch for https://sourceforge.net/apps/trac/bigdata/ticket/342 (Too much IO scatter for TERMS index). This is a branch off of the TERMS_REFACTOR_BRANCH.
Here is my summary of what needs to be changed. Mostly, this requires importing some classes which were dropped during the TERMS refactor back in from the QUADS branch. We also have to create a distinction between a TermId, which I think should once again refer to an IV which is a key into the ID2TERM index, and an IV which is a key into the "TERMS" index. I am tempted to rename the TERMS index as the BLOBS index, which would give us a BlobIV for that index. Given that the the TERMS index has too much IO scatter, it this rename seems to be inline with using it primarily for large objects (say 256 bytes and up). The concept of the "NullIV" should go to the ID2TERM' IVs where it can once again be represented by a 0L termId. This is significantly simpler than inserting 4 distinct NullIVs into the TERMS index. Outside of the re-imported classes and the introduction of a BlobIV, most of the changes will be restricted to the LexiconRelation.
I plan to go with the introduction of the "extension" byte describe above for the TERMS index. This will provide extensibility for additional storage options, including the inlining of URIs with a combination of a "byte" or "short" namespaceIV and a Unicode localName and specialized storage for block oriented cloud aware storage systems such as Amazon's S3. Given that we will restrict the use of the TERMS index to RDF Values with more than (say) 256 characters of data, this additional byte in the key for the TERMS index will be lost in the noise. Since there will be far fewer entries in the TERMS index, the possibility of a hash collision bucket becoming full is exceedingly remote (the excellent distribution of hash codes is the reason why the TERMS index is causing too much IO) but we could always take one more byte for the counter, making it into a short. That would be an 8 byte TERMS index key, which is what we already have for the ID2TERM index (actually, it's probably 9 bytes since it includes the flags byte as well).
{{{
- LexiconRelation: 3 indices (TERM2ID, ID2TERM, TERMS/BLOBS)
- LexiconRelation#newAccessPath() will have to support point lookup against ID2TERM and TERMS.
- Recover the write tasks, write procedures, and unit tests for the TERM2ID and ID2TERM indices from the QUADS branch.
- Update the scale-out data loader (recover the classes which handle the TERM2ID and ID2TERM indices). I will also have to change the latch/guard conditions since both TERM2ID and TERMS are assigning IVs and that is what we need to wait on for various events.
- The text index should be ok, but review the integration anyway.
- NullIVs should be modeled as a 0L termId for the ID2TERM index rather than using the TERMS index. The TERMS index does not need to have the "NullIV" versions of a URI, BNode, Literal, or SID inserted when it is created.
}}}
Configuration file settings will also need to be recovered for scale-out for the TERM2ID and ID2TERM indices. Some thought should be given to the buffering of large objects for the TERMS index in the scale-out data loader. Assuming that we choose the threshold for the ID2TERM/TERMS index appropriately, we should observe a moderate amount of activity on that index write pipeline. But very large RDF Values (megabytes) should probably be flushed through immediately. This suggests bounding the asynchronous index write pipeline on memory consumed and not (just) the #of tuples buffered (chunkSize).
This branch will be merged back to the TERMS_REFACTOR_BRANCH once it is pass its test suite.

Log Message:

See https://sourceforge.net/apps/trac/bigdata/ticket/349 (TermIdEncoder limiting #of RDF Values on the Journal)
- done. VTE Removed 'TODO' about TermIdEncoder (already gone in the
development branch). Note: the sole remaining reference to
TermIdEncoder is from Term2IdWriteProc#apply(). Therefore there
should not be any other assumptions in the code which could be
effected by
- done. Update AbstractTripleStore.Options.TERMID_BITS_TO_REVERSE
to reflect that this option is only used in scale-out.
- done. Update AbstractTripleStore.Options.TERMID_BITS_TO_REVERSE
to no longer reflect the stealing of the sign bits as the VTE is
now encoded with the flags byte of the IV rather than in the long
termId.
- done. Modify LexiconRelation#addTerms(), Term2IdWriteProc, and
Term2IdWriteTask such that the TermIdEncoder is NOT used for
standalone. This is done by forcing termIdBitsToReverse to ZERO
(0) unless in scale-out and then NOT using the TermIdEncoder when
termIdBitsToReverse is ZERO (0). Note that NOT using
TermIdEncoder should be a NOP once it is 64-bits clean so this
optimization is not strictly necessary.

Revision: 4863
http://bigdata.svn.sourceforge.net/bigdata/?rev=4863&view=rev
Author: thompsonbry
Date: 2011-07-08 14:48:19 +0000 (Fri, 08 Jul 2011)
Log Message:
-----------
See https://sourceforge.net/apps/trac/bigdata/ticket/124 (TermIdEncoder needs to use more bits now that ITermIdCodes is gone).
This commit resolves the issue in both the 1.0.0 release branch and the current development branch.
- done. Modify TermIdEncoder to use all bits for pid and ctr,
rejecting only 0L, which is still reserved for null. Modify the
unit tests to verify that TermIdEncoder is now 32-bit clean for
both the pid and ctr values and test encode/decode against random
non-zero 64bit integers.
Files changed: TermIdEncoder, TestTermIdEncoder
- done. Modify BTree.PartitionedCounter to (a) permit the partition
local counter to wrap around, but not to come all the way back to
zero again; and (b) to use a 32-bit clean method to form the
int64 counter from the partitionId and the local counter value.
- done. Modify BTree.Counter to allow the counter to wrap through
the negative long integer values until it would reach ZERO (0L)
again and write unit tests for same.
Files changed: BTree, TestIndexCounter,
- done. Review the data structures which persist the partition
identifier to see if they are using packed (long) integers for
the pid. That will limit us to Integer.MAX_VALUE shards, which
is not all that bad. [it looks like things are 32-bit clean for
pid.]

Author: thompsonbry

Log Message:
-----------
Modified the test to explicitly set a flag if there are no errors by the time we interrupt the running tasks. This allows the test to report failure only for errors encountered during normal execution of tasks and filters out any failures which might arise from the interruption of a large number of concurrent tasks. This is in response to [1].

Revision: 4890
http://bigdata.svn.sourceforge.net/bigdata/?rev=4890&view=rev
Author: thompsonbry
Date: 2011-07-12 14:22:46 +0000 (Tue, 12 Jul 2011)
Log Message:
-----------
I have modified BigdataValueFactoryImpl per the change recommended above.
I have integrated the unit test into the test suite for TestBigdataSailWithQuads.
I have extended the test suite for the BigdataValueFactoryImpl to verify the behavior when a DummyIV is used.
These changes have been applied to the 1.0.0 release branch and to the current development branch.
See https://sourceforge.net/apps/trac/bigdata/ticket/348

+This is a bigdata (R) release. This release is capable of loading 1B triples in
+under one hour on a 15 node cluster. JDK 1.6 is required.
+
+Bigdata(R) is a horizontally scaled open source architecture for indexed data
+with an emphasis on semantic web data architectures. Bigdata operates in both
+a single machine mode (Journal) and a cluster mode (Federation). The Journal
+provides fast scalable ACID indexed storage for very large data sets. The
+federation provides fast scalable shard-wise parallel indexed storage using
+dynamic sharding and shard-wise ACID updates. Both platforms support fully
+concurrent readers with snapshot isolation.
+
+Distributed processing offers greater throughput but does not reduce query or
+update latency. Choose the Journal when the anticipated scale and throughput
+requirements permit. Choose the Federation when the administrative and machine
+overhead associated with operating a cluster is an acceptable tradeoff to have
+essentially unlimited data scaling and throughput.
+
+See [1,2,8] for instructions on installing bigdata(R), [4] for the javadoc, and
+[3,5,6] for news, questions, and the latest developments. For more information
+about SYSTAP, LLC and bigdata, see [7].
+
+Starting with this release, we offer a WAR artifact [8] for easy installation of
+the Journal mode database. For custom development and cluster installations we
+recommend checking out the code from SVN using the tag for this release. The
+code will build automatically under eclipse. You can also build the code using
+the ant script. The cluster installer requires the use of the ant script.
+
+You can checkout this release from the following URL:
+
+https://bigdata.svn.sourceforge.net/svnroot/bigdata/tags/BIGDATA_RELEASE_1_0_1
+
+Bug fixes:
+
+ - https://sourceforge.net/apps/trac/bigdata/ticket/349 (TermIdEncoder limits
+ Journal to 2B distinct RDF Values per triple/quad store instance).
+
+ - https://sourceforge.net/apps/trac/bigdata/ticket/124 (TermIdEncoder should
+ use more bits for scale-out).
+
+ - https://sourceforge.net/apps/trac/bigdata/ticket/107 (Unicode clean schema
+ names in the sparse row store).
+
+ - https://sourceforge.net/apps/trac/bigdata/ticket/348 (BigdataValueFactory.asValue()
+ must return new instance when DummyIV is used).
+
+New features in 1.0.x release:
+
+- Single machine data storage to ~50B triples/quads (RWStore);
+- Simple embedded and/or webapp deployment (NanoSparqlServer);
+- 100% native SPARQL 1.0 evaluation with lots of query optimizations;
+
+Feature summary:
+
+- Triples, quads, or triples with provenance (SIDs);
+- Fast RDFS+ inference and truth maintenance;
+- Clustered data storage is essentially unlimited;
+- Fast statement level provenance mode (SIDs).
+
+The road map [3] for the next releases includes:
+
+- High-volume analytic query and SPARQL 1.1 query, including aggregations;
+- Simplified deployment, configuration, and administration for clusters; and
+- High availability for the journal and the cluster.

+
+Bigdata(R) is a horizontally-scaled, general purpose storage and computing fabric
+for ordered data (B+Trees), designed to operate on either a single server or a
+cluster of commodity hardware. Bigdata(R) uses dynamically partitioned key-range
+shards in order to remove any realistic scaling limits - in principle, bigdata\xAE
+may be deployed on 10s, 100s, or even thousands of machines and new capacity may
+be added incrementally without requiring the full reload of all data. The bigdata\xAE
+RDF database supports RDFS and OWL Lite reasoning, high-level query (SPARQL),
+and datum level provenance.

Revision: 4898
http://bigdata.svn.sourceforge.net/bigdata/?rev=4898&view=rev
Author: thompsonbry
Date: 2011-07-12 17:39:31 +0000 (Tue, 12 Jul 2011)
Log Message:
-----------
The change described above fixes the original problem. However, it uncovered an issue where equals() was not symmetric when one bigdata value had a "dummy" IV. I have extended the test coverage for this, fixed the various concrete BigdatsValue classes and run through the test suite locally.
See https://sourceforge.net/apps/trac/bigdata/ticket/348

Revision: 4899
http://bigdata.svn.sourceforge.net/bigdata/?rev=4899&view=rev
Author: thompsonbry
Date: 2011-07-12 18:56:14 +0000 (Tue, 12 Jul 2011)
Log Message:
-----------
Bug fix to BigdataValueFactory.asValue() in the 1.0.0 release branch. It was always returning a new value if the given value was not a TermId. This was causing the SIDs tests to fail since a SidIV is not a TermId.
Test setup/tear down changes to TestFactory in the 1.0.0 release branch and in the development branch. The fixture reference is now cleared when the test is torn down to prevent memory leaks during CI.

Log Message:
-----------
Added support for collecting OSX performance counters to both the 1.0.0 release branch for the 1.0.1 dot release and to the current development branch. This closes out [1]. However, note that we are not able to collect IO Wait under OSX. Nor are we able to report the IO statistics broken out by reads and writes. See [1] for more details on this. It is a problem with the OSX command line utilities for reporting performance counters.
