0696696cf6 MCOL-894 Upmerged post review changes. 
Raised the default for orderby threads from 4 to 16.
    Removed if LIMIT check block in makeVtableModeSteps().
    Removed a duplicate of TimeCompare class and methods.

MCOL-3536 Upmerged the change.

MCOL-894 Post review changes.
    Uncomment if LIMIT check block in makeVtableModeSteps().

    TupleAnnexStep dtor now uses vector::size() as a boundary.

    Removed useless try-catch blocks.

    executeParallelOrderBy() now calculates rowSize only once.

    Removed forward declaration in the unexisting namespace.

    Trim UTs a bit.

7b5e5f0eb6 MCOL-894 Upmerged the fist part of the patch into develop. 
MCOL-894 Add default values in Compare and CSEP ctors to activate UTF-8 sorting
    properly.

MCOL-894 Unit tests to build a framework for a new parallel sorting.

MCOL-894 Finished with parallel workers invocation.
     The implementation lacks final aggregation step.

MCOL-894 TupleAnnexStep's init and destructor are now parallel execution aware.

    Implemented final merging step for parallel execution finalizeParallelOrderBy().

    Templated unit test to use it with arbitrary number of rows, threads.

Reuse LimitedOrderBy in the final step

MCOL-894 Cleaned up finalizeParallelOrderBy.

MCOL-894 Add and propagate thread variable that controls a number of threads.

    Optimized comparators used for sorting and add corresponding UTs.

    Refactored TupleAnnexStep::finalizeParallelOrderByDistinct.

    Parallel sorting methods now preallocates memory in batches.

MCOL-894 Fixed comparator for StringCompare.

2. Explicitly set array bounds for Row::hash() and Row::equals().

4b9d046c6e Fully resolve potentially ambiguous symbols by removing using namespace statements from headers which have a cascading effect. This causes potential behavior changes when switching to c++11 since symbols can be exported from std and boost while both have been imported into the global namespace. 2019-04-29 01:21:15 -05:00

947eaaef26 MCOL-901 group_concat() uses only a subset of unique values 
b/c an incorrect number of key columns was used whilst
        initializing Eq() struct. The regression caused by
        changes made for MCOL-1829 so I revised the changes
        made. Now LimitedOrderBy::getKeyLength() returns an
        actual key columns count.

7b4cec5757 MCOL-1829 Subquery with limited order by could potentially return onordered set. 
There were two code mistakes: Eq::operator() always returned true for
    any pair and Hasher::operator() always returned 0 as a key.
