---------------------------------------
Status: Patch Available (was: Open)
> Eliminate temporary object[] allocations in ColumnDefinition::hashCode
> ----------------------------------------------------------------------
>
> Key: CASSANDRA-11422
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11422
> Project: Cassandra
> Issue Type: Sub-task
> Components: Core
> Reporter: Nitsan Wakart
> Assignee: 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:
