Resolution: Fixed
> TTL_DELETE CDC event to use batch mutation
> ------------------------------------------
>
> Key: PHOENIX-7677
> URL: https://issues.apache.org/jira/browse/PHOENIX-7677
> Project: Phoenix
> Issue Type: Improvement
> Reporter: Viraj Jasani
> Assignee: Viraj Jasani
> Priority: Major
> Fix For: 5.3.0
>
>
> 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.
