[jira] [Created] (FLINK-3758) Add possibility to register
accumulators in custom triggers
Konstantin Knauf created FLINK-3758:
---------------------------------------
Summary: Add possibility to register accumulators in custom triggers
Key: FLINK-3758
URL: https://issues.apache.org/jira/browse/FLINK-3758
Project: Flink
Issue Type: Improvement
Reporter: Konstantin Knauf
Priority: Minor
For monitoring purposes it would be nice to be able to to use accumulators in custom trigger functions.
Basically, the trigger context could just expose {{getAccumulator}} of {{RuntimeContext}} or does this create problems I am not aware of?
Adding accumulators in a trigger function is more difficult, I think, but that's not really neccessary as the accummulator could just be added in some other upstream operator.
