Bret McGuire updated CASSJAVA-68:
---------------------------------
Resolution: Fixed
Status: Resolved (was: Triage Needed)
> Improve DefaultCodecRegistry.CacheKey#hashCode() to eliminate Object[]
> allocation
> ---------------------------------------------------------------------------------
>
> Key: CASSJAVA-68
> URL: https://issues.apache.org/jira/browse/CASSJAVA-68
> Project: Apache Cassandra Java driver
> Issue Type: Improvement
> Components: Core
> Reporter: Jane He
> Priority: Normal
> Fix For: 4.19.1
>
> Time Spent: 40m
> Remaining Estimate: 0h
>
> From [~tatu-at-datastax] : Profiling showed significant {{Object[]}}
> allocations at {{DefaultCodecRegistry.CacheKey#hashCode()}} (since
> {{Object.hashCode(Object... args)}} takes varargs which gets converted into
> {{{}Object[]{}}}) so figured out it's worth improving upon.
>
> Also, another [ticket|https://datastax-oss.atlassian.net/browse/JAVA-3073]
> and [PR|https://github.com/apache/cassandra-java-driver/pull/1644] is about
> `Objects.hash` performance issue discovered by profiling. A quick text search
> shows that we have 60+ `Objects.hash` usage in our codebase. Maybe we should
> consider fixing other `Objects.hash` usages, too.
