aitozi created FLINK-10996:
------------------------------
Summary: Enable state ttl in cep
Key: FLINK-10996
URL: https://issues.apache.org/jira/browse/FLINK-10996
Project: Flink
Issue Type: Improvement
Components: CEP
Affects Versions: 1.7.1
Reporter: aitozi
Assignee: aitozi
Fix For: 1.7.1
In flink cep, although the within clause can clean up the data when data is expire. But If the specific key data never come again, the partial matched data will not be deleted again which will lead to the state leak. With the state ttl feature support by flink runtime, we has the ability to expire the correlative data asyncly .
