Summary: FLIP-168: Speculative Execution for Batch Job
Key: FLINK-28131
URL: https://issues.apache.org/jira/browse/FLINK-28131
Project: Flink
Issue Type: New Feature
Components: Runtime / Coordination
Reporter: Zhu Zhu
Fix For: 1.16.0
Speculative executions is helpful to mitigate slow tasks caused by problematic
nodes. The basic idea is to start mirror tasks on other nodes when a slow task
is detected. The mirror task processes the same input data and produces the
same data as the original task.
