Assignee: (was: Kevin Doran)
> Evaluate NiFi's default JVM GC args. Consider adding UseStringDeduplication
> ---------------------------------------------------------------------------
>
> Key: NIFI-15091
> URL: https://issues.apache.org/jira/browse/NIFI-15091
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Configuration
> Reporter: Kevin Doran
> Priority: Minor
>
> There was recently an [interesting
> discussion|https://github.com/apache/nifi/pull/10372#issuecomment-3362326306]
> on the use of {{-XX:+UseStringDeduplication}} benefiting NiFi clusters that
> process many FlowFiles containing many FlowFile attributes, potentially with
> duplicate values.
> At a glance, it seems that many NiFi use cases would benefit from enabling
> the {{UseStringDeduplication}} JVM GC arg, and there is probably little to no
> downside or risk to enabling it by default, even for use cases might not
> benefit.
> We should profile one or more representative flows in NiFi with and without
> this flag, quantify the potential savings, and, if merited, consider enabling
> this GC option by default in the JVM args of {{bootstrap.conf}} sourced by
> {{nifi.sh}}.
