Stefan Richter created FLINK-11417: -------------------------------------- Summary: Make access to ExecutionGraph single threaded from JobMaster main thread Key: FLINK-11417 URL: https://issues.apache.org/jira/browse/FLINK-11417 Project: Flink Issue Type: Sub-task Components: Distributed Coordination Reporter: Stefan Richter Assignee: Stefan Richter
To simplify future developments in scheduling, we should re-design the threading model for interaction with the {{ExecutionGraph}} and its sub-components to a single threaded approach. In this model, expensive tasks will still be performed by background threads so that the JM main thread will never block. However, all resulting modifications and interaction with the EG itself should only go through the JM main thread. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
