Subject Change in asterixdb[master]: Enable the parallel sort in the optimizor.
Date Mon, 06 Feb 2017 10:45:15 GMT
Hello Jenkins,

I'd like you to reexamine a change.  Please visit

    https://asterix-gerrit.ics.uci.edu/1381

to look at the new patch set (#40).

Change subject: Enable the parallel sort in the optimizor.
......................................................................

Enable the parallel sort in the optimizor.

Based on the MaterializingForwardOperatorDescriptor, enable the parallel sort in full round.
1. Add LogicalOperator Foward to enable MaterializingForwardOperatorDescriptor in the logical
optimizor.
2. Introduce hint "psort" before sort to enable the user to use parallel sort.
3. Add the IntroduceParallelSortRule to introduce ReplicateOperator, AggregateOperator, ForwardOperator
before SortOperator.
4. Apply ParallelStableSortPOperator into SortOperator if the following conditions are satisfied:
   a. Single column sort.
   b. non-topK condition inlined.
5. Add EnforcePreAdHocReplicateRule to guarantee the consistency of the replicate with forward.
6. Add and partially enable the opt/rtTest cases, including:
   a. Psort on full records.
   b. Psort on a join results.
   c. Nested psort within a subplan below a secondary sort or psort.
7. Use binarySearch in two RangePartitioners.
