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. -- This message was sent by Atlassian Jira (v8.20.10#820010)
