Subject CEP Pattern detection progressively slower
Date Tue, 11 Apr 2017 17:57:04 GMT
While trying to use Pattern detection on KeyedStream, list of unique keys
encountered, keeps accumulating in AbstractKeyedCEPPatternOperator.java. On
encountering watermarks these accumulated keys are looped over to detect
patterns. This causes spike in CPU usage and progressively gets slower.

Is this a known issue
Are there any workarounds?

This happens with 1.2.0 version
