> Idx memory allocation fix
> - Includes a modification to core - MemStore was added with a numKeyValues
> query
> - It optimizes the number of memory allocation required to rebuild the
> index. This is a major fix - it reduces the heap fragmentation and helped
> postpone/fix (not yet sure which of those) the region server crashing due to
> those long GC periods on a write-intensive setup
