> FLIP-224: Blocklist Mechanism
> -----------------------------
>
> Key: FLINK-28130
> URL: https://issues.apache.org/jira/browse/FLINK-28130
> Project: Flink
> Issue Type: New Feature
> Components: Runtime / Coordination
> Affects Versions: 1.16.0
> Reporter: Lijie Wang
> Assignee: Lijie Wang
> Priority: Major
>
> In order to support speculative execution for batch
> jobs([FLIP-168|https://cwiki.apache.org/confluence/display/FLINK/FLIP-168%3A+Speculative+Execution+for+Batch+Job]),
> we need a mechanism to block resources on nodes where the slow tasks are
> located. We propose to introduce a blocklist mechanism as follows: Once a
> node is marked as blocked, future slots should not be allocated from the
> blocked node, but the slots that are already allocated will not be affected.
> More details see
> [FLIP-224|https://cwiki.apache.org/confluence/display/FLINK/FLIP-224%3A+Blocklist+Mechanism]
> This is the umbrella ticket to track all the changes of this feature.
