Hi All,
We've been experimenting with `MATCH_RECOGNIZE` clause on Flink 1.8. We
tried to have a pattern match within one hour. According to
https://ci.apache.org/projects/flink/flink-docs-stable/dev/table/streaming/match_recognize.html#time-constraint
,
using `WITHIN` will control the memory usage. We've been running queries
using CEP for almost one week and memory usage is not going down. Are we
missing something?
