-----------------------------------------
Summary: Eliminate temporary object[] allocations in
ColumnDefinition::hashCode
Key: CASSANDRA-11422
URL: https://issues.apache.org/jira/browse/CASSANDRA-11422
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Nitsan Wakart
ColumnDefinition::hashCode currently calls Objects.hashCode(Object...)
This triggers the allocation of a short lived Object[] which is not eliminated
by EscapeAnalysis. I have implemented a fix by inlining the hashcode logic and
also added a caching hashcode field. This improved performance on the read
workload.
Fix is available here:
