Viraj Jasani updated PHOENIX-7677:
----------------------------------
Description:
Inserting TTL_DELETE CDC event from CompactionScanner for single expired row at
a time can cause slight degradation to the write workload to the CDC index
table.
To improve the performance of inserting TTL_DELETE events, CompactionScanner
can accumulate 50 mutations by default and perform the batchMutate(). Any
mutations that are not inserted into the CDC index should be inserted with
batchMutate() while closing the CompactionScanner.
