Ralph Goers commented on LOG4J2-1296:
-------------------------------------
I think saying "the whole epic goes out the window" is a bit strong. Even
reducing the number of objects created by 80-90 % is pretty impressive.
> Add MessageFactory that reuses a cached Message instance

> Key: LOG4J2-1296
> URL: https://issues.apache.org/jira/browse/LOG4J2-1296
> Project: Log4j 2
> Issue Type: New Feature
> Components: API
> Affects Versions: 2.5
> Reporter: Remko Popma
> Assignee: Remko Popma
>
> As discussed in LOG4J2-1270, all current MessageFactory implementations
> create new temporary Message objects. A GC-free configuration needs a
> different MessageFactory that reuses Message instances.
> When Messages are being reused, async logging components need to be aware of
> this and ensure the Message _content_ (rather than the Message instance
> itself) is passed to the background thread. However, Messages that are not
> reusable should be passed to the background thread unchanged.
