Aljoscha Krettek closed FLINK-17766. ------------------------------------ Resolution: Fixed master: 59714b9d6addb1dbf2171cab937a0e3fec52f2b1 > Use checkpoint lock instead of fine-grained locking in Kafka AbstractFetcher > ---------------------------------------------------------------------------- > > Key: FLINK-17766 > URL: https://issues.apache.org/jira/browse/FLINK-17766 > Project: Flink > Issue Type: Sub-task > Components: Connectors / Kafka > Reporter: Aljoscha Krettek > Assignee: Aljoscha Krettek > Priority: Major > Fix For: 1.11.0 > > > In {{emitRecordsWithTimestamps()}}, we are currently locking on the partition > state object itself to prevent concurrent access (and to make sure that > changes are visible across threads). However, after recent changes > (FLINK-17307) we hold the checkpoint lock for emitting the whole "bundle" of > records from Kafka. We can now also just use the checkpoint lock in the > periodic emitter callback and then don't need the fine-grained locking on the > state for record emission. -- This message was sent by Atlassian Jira (v8.3.4#803005)
