Michael W Moser updated NIFI-15039:
-----------------------------------
Status: Patch Available (was: In Progress)
> Replace usage of Enum.values() when called often
> ------------------------------------------------
>
> Key: NIFI-15039
> URL: https://issues.apache.org/jira/browse/NIFI-15039
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Michael W Moser
> Assignee: Michael W Moser
> Priority: Minor
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Each call to Enum.values() copies the Enum's values into a new array. When
> Enum.values() is called often, this causes extra unnecessary garbage
> collection pressure.
> Find instances where Enum.values() is called a lot and provide an
> improvement. Do not include cases where Enum.values() is called in exception
> handling or during initialization.
> An interesting blog that explains the values() behavior for one use case:
