1. Make PredicateOperator::setOpType() function wide decimal aware.
2. Added support for wide decimal in jlf_subquery.cpp::getColumnValue()
used in scalar subqueries.
3. Fixed the column index used for fetching wide decimal values from a Row
when a wide decimal field is used in the order by clause.
Removed uint128 from joblist/lbidlist.*
Another toString() method for wide-decimal that is EMPTY/NULL aware
Unified decimal processing in WF functions
Fixed a potential issue in EqualCompData::operator() for
wide-decimal processing
Fixed some signedness warnings
For now it consists of only:
using int128_t = __int128;
using uint128_t = unsigned __int128;
All new privitive data types should go into this file in the future.
WF::percentile runtime threw an exception b/c of wrong DT deduced from its argument
Replaced literals with constants
Tought WF_sum_avg::checkSumLimit to use refs instead of values
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.
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.
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.
