FlinkCEP

Hi

It's been over 5 years since I last did anything with FlinkCEP and Flink.

Has there been any significant development in FlinkCEP during this time?

Hi,
As Zhongqiang said, the CEP API is stable. Besides that, there are some
changes worth mentioning：
1. https://issues.apache.org/jira/browse/FLINK-23890 Since flink 1.16.0,
the timer creation is optimized which can incredibly reduce the resource
usage of cep operator given same workload.
2. https://issues.apache.org/jira/browse/FLINK-27392 This jira supports
defining window among adjacent sub-pattern.
3. https://issues.apache.org/jira/browse/FLINK-26941 This jira enables
Pattern to end with notFollowedBy with window

Best,
Biao Geng
