Revision: 7768
http://bigdata.svn.sourceforge.net/bigdata/?rev=7768&view=rev
Author: thompsonbry
Date: 2014-01-10 22:55:17 +0000 (Fri, 10 Jan 2014)
Log Message:
-----------
Bug fix for complex OPTIONAL groups and the RTO. The root cause was a failure to visit the children of the JoinGraph node when assigning BOpStats objects to the top-level query. The fix was to AbstractRunningQuery#populateStatsMap().

-----------
Modified the committed code to allow out of order evaluation. This gets BSBM Q5 to pass. The root cause is a conditional routing operation that is not maintaining the ordering. I think that the fix is to do the materialization non-conditionally and NOT attach the FILTER to the JOIN. I have allowed out of order evaluation until I can talk this through with MikeP.

Modified AbstractRunningQuery.getChildren() to be recursive since we were missing any sub-queries that were executed from within a named subquery. This showed up in the explain view of govtrack/queries/query0011.rq.

Updated javadoc on the receive and replicate and robust send tasks in QuorumPipelineImpl.
Renamed the local and remote futures as futLoc and futRmt. The local future is either the HASendService or the HAReceiveService (with an inner HASendService). The remote future is the RMI to the HAPipeline interface for receiveAndReplicate() or receive().

Log Message:
-----------
The RTO now supports FILTERs on required joins when those filters have materialization requirements. This is the subject of #257, which is now closed. Over time we will probably refactor the RTO to operate directly on the AST nodes (e.g., StatementPatternNode versus SPOPredicate), but it currently handles conditional materialization pipelines just fine.
There are currently two different ways in which a cutoff join can be evaluated. One uses a single pipeline join and carefully controls the execution of that join to obtain an estimated cardinality. This is the historical method.
The other can handle a sequence of operators. A pipeline join is generated followed by whatever operators are required to materialize variable bindings and evaluate filters. Finally, a SLICE is appended to the query plan to limit the output. When the query is executed, a rowid column is injected into the source solutions. This is used to correctly correlate the #of input solutions required to produce a given #of output solutions and hence obtain the estimated cardinality of the join through cutoff evaluation.
Some slight differences in the resulting plans and runtime behavior have been observed when all queries
See #257 (Support BOP fragments in the RTO)

+ * Hi Bryan:
+ *
+ * I would expect the remote task to complete and return, despite the caller being interrupted. The JERI subsystem (I\xD5m guessing the invocation layer, but it might be the transport layer) might log an exception when it tried to return, but there was nobody on the calling end.
+ *
+ * That\xD5s consistent with a worst-case failure, where the caller drops off the network. How is the called service supposed to know what happened to the caller?
+ *
+ * In the case of a typical short operation, I wouldn\xD5t see that as a big issue, as the wasted computational effort on the service side won\xD5t be consequential.
+ *
+ * In the case of a long-running operation where it becomes more likely that the caller wants to stop or cancel an operation (in addition to the possibility of having it interrupted), I\xD5d try to break it into a series of operations (chunks), or setup an ongoing notification or update protocol. You probably want to do that anyway, because clients probably would like to see interim updates while a long operation is in process.
+ *
+ * Unfortunately, I don\xD5t think these kinds of things can be reasonably handled in a communication layer - the application almost always needs to be involved in the resolution of a problem when we have a service-oriented system.
