---------------------------------------------
Summary: Optimize chunk cache
Key: CASSANDRA-18855
URL: https://issues.apache.org/jira/browse/CASSANDRA-18855
Project: Cassandra
Issue Type: Improvement
Components: Local/Caching
Reporter: Jacek Lewandowski
Assignee: Jacek Lewandowski
1. Chunk cache hashcode computation can be costly as it is on a hot path, would
be good to precompute it (as well as hashcode of some other immutable classes).
2. Invalidation of a file can be costly if the cache is really large. We should
rather rely on the automatic eviction of unused entries.
