Are there processors that can share/collect flowfiles across specified time-windows?

[#1]

I see that MergeContent can merge multiple flowfiles into one with specified size or flowfile count semantics. Is there a processor that does this based on elapsed time instead?

Two answers:

• For a rolling window look into "DistributedSetCache" as that allows the most recent X events to be lookedup
• for time chunking this jira question(also asked by you) resolves it https://issues.apache.org/jira/browse/NIFI-1775
