Description

Currently the Wait/Notify processors write out every signal in the cache, not just the signal that triggers the release of the flow file. This can result in flow files with tens of thousands of attributes which can put pressure on the NiFi JVM heap.

It would be good to be able to have only the signal that triggers the release as an added attribute.
