Venki Korukanti updated DRILL-1992:
-----------------------------------
Attachment: DRILL-1992-2.patch
Thanks Aman for reviewing. Changed "memoryAllocated" type to long in all
places. Variable length vectors template is missing the getCapacity()
implementation (although its superclass BaseDataValueVector has an
implementation, it doesn't include offset vector capacity). For fixed types,
implementation is in superclass BaseDataValueVector.
> Add more stats for HashJoinBatch and HashAggBatch
