Zhu Zhu updated FLINK-22677: ---------------------------- Affects Version/s: 1.14.0 > Scheduler should invoke ShuffleMaster#registerPartitionWithProducer by a real > asynchronous fashion > -------------------------------------------------------------------------------------------------- > > Key: FLINK-22677 > URL: https://issues.apache.org/jira/browse/FLINK-22677 > Project: Flink > Issue Type: Sub-task > Components: Runtime / Coordination > Affects Versions: 1.14.0 > Reporter: Jin Xing > Assignee: Zhu Zhu > Priority: Major > > Current scheduler enforces a synchronous registration though the API of > ShuffleMaster#registerPartitionWithProducer returns a CompletableFuture. In > scenario of remote shuffle service, the talk between ShuffleMaster and remote > cluster tends to be expensive. A synchronous registration risks to block main > thread potentially and might cause negative side effects like heartbeat > timeout. Additionally, expensive synchronous invokes to remote could > bottleneck the throughput for applying shuffle resource, especially for batch > jobs with complicated DAGs; -- This message was sent by Atlassian Jira (v8.3.4#803005)
