Bowen Li updated FLINK-8560: ---------------------------- Summary: Access to the current key in ProcessFunction#OnTimerContext after keyBy() (was: Access to the current key in ProcessFunction after keyBy()) > Access to the current key in ProcessFunction#OnTimerContext after keyBy() > ------------------------------------------------------------------------- > > Key: FLINK-8560 > URL: https://issues.apache.org/jira/browse/FLINK-8560 > Project: Flink > Issue Type: Wish > Components: DataStream API > Reporter: Jürgen Thomann > Assignee: Bowen Li > Priority: Minor > > Currently it is required to store the key of a keyBy() in the processElement > method to have access to it in the OnTimerContext. > This is not so good as you have to check in the processElement method for > every element if the key is already stored and set it if it's not already set. > A possible solution would adding OnTimerContext#getCurrentKey() or a similar > method. Maybe having it in the open() method could maybe work as well. > http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Getting-Key-from-keyBy-in-ProcessFunction-tt18126.html -- This message was sent by Atlassian JIRA (v7.6.3#76005)
