Subject Catalyst Expression(s) - Cleanup
Date Wed, 25 Jan 2017 18:13:47 GMT
Is there currently any way to receive a signal when an Expression will no longer receive any
rows so internal resources can be cleaned up?

I have seen Generators are allowed to terminate() but my Expression(s) do not need to emit
0..N rows.
