Subject [jira] [Commented] (FLINK-11139) stream non window join support state ttl
Date Thu, 13 Dec 2018 16:11:00 GMT

Fabian Hueske commented on FLINK-11139:
---------------------------------------

[~zhaoshijie] Which join are you using? One of the built-in joins of DataStream API or Table
API / SQL and if so, which one? Can you point to the documentation?
As far as I know, none of the join implementations relies on the recently added State TTL
feature.

> stream non window join function use timer to delete expired data,it is ok for small
amount of data or short expiration time,but it will be OOM(too many timer)on taskManger
 when there  is a long expiration time and  a large amount of data。In fact, table module
other state function has same problem,I would like to contribute to fix it。
