Zhu Zhu created an issue   Flink / FLINK-28271 Add configuration options for speculative scheduler Issue Type: Sub-task Assignee: Unassigned Components: Runtime / Configuration Created: 28/Jun/22 03:55 Fix Versions: 1.16.0 Priority: Major Reporter: Zhu Zhu Following config options are needed for speculative scheduler: jobmanager.adaptive-batch-scheduler.speculative.enabled, default to "false". It controls whether to enable speculative execution. Note that speculative execution only works with AdaptiveBatchScheduler, which requires "jobmanager.scheduler" to be set to "AdaptiveBatch". jobmanager.adaptive-batch-scheduler.speculative.max-concurrent-executions, default to "2". It controls how many executions (including the original one and speculative ones) of an ExecutionVertex can execute at the same time. jobmanager.adaptive-batch-scheduler.speculative.block-slow-node-duration, default to "1 min". It controls how long an identified slow node should be blocked for. Add Comment   This message was sent by Atlassian Jira (v8.20.10#820010-sha1:ace47f9)
