> URL: https://issues.apache.org/jira/browse/NIFI-4504

> Reporter: Jon Kessler
> Assignee: Michael Moser
> Priority: Minor
> Fix For: 1.5.0
>
>
> Typical map implementations return the value that was removed when performing
> a remove. Because you couldn't update the existing remove methods without it
> being a breaking change I suggest adding new versions of the remove and
> removeByPattern methods that return the removed value(s).
> These changes should also be applied up the chain to any class that makes use
> of these classes such as the MapCacheServer and
> AtomicDistributedMapCacheClient.
