Summary: Pool Merge Iterators
Key: CASSANDRA-15392
URL: https://issues.apache.org/jira/browse/CASSANDRA-15392
Project: Cassandra
Issue Type: Sub-task
Components: Local/Compaction
Reporter: Blake Eggleston
Assignee: Blake Eggleston
By pooling merge iterators, instead of creating new ones each time we need
them, we can reduce garbage on the compaction and read paths under relevant
workloads by ~4% in many cases.
