Aldrin Piri commented on NIFI-440:
----------------------------------

+1 on this.  Definitely helpful to have a way to call this out explicitly and in a consistent manner.

> From Joe:
> We should also consider an annotation that lets the developer indicate something like "PerformanceConsider" whereby they can signal for the UI and documentation an important performance note for someone building the flow to consider. For example, the processor EvaluateJSONPath has a note indicating it reads the entire object into memory to do its thing. This is important because it means there is a concern one should have in mind for object size and concurrency and so on. Totally feasible one might warn of disk usage or cpu usage for a given case.
