Carter Kozak reassigned LOG4J2-2752:
------------------------------------
Assignee: Carter Kozak
> Reduce memory overhead using thread locals with non-reusable messages
> ---------------------------------------------------------------------
>
> Key: LOG4J2-2752
> URL: https://issues.apache.org/jira/browse/LOG4J2-2752
> Project: Log4j 2
> Issue Type: Improvement
> Affects Versions: 2.13.0
> Reporter: Carter Kozak
> Assignee: Carter Kozak
> Priority: Major
>
> Using ParameterizedMessageFactory (non-reusable) with thread locals for
> asynchronous logging results in unused object parameter arrays and empty
> StringBuilder buffers.
> We can update RingBufferLogEvent and MutableLogEvent to create both the
> StringBuilder buffer and parameter array lazily in order to avoid the memory
> overhead entirely when reusable messages are not used.
