> Key: FLINK-27222
> URL: https://issues.apache.org/jira/browse/FLINK-27222
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination
> Affects Versions: 1.15.0
> Reporter: Chesnay Schepler
> Assignee: Chesnay Schepler
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.15.0, 1.16.0
>
>
> Local recovery relies on knowing the allocation id of the last deployment. To
> that end we iterate over all previous execution attempts and use the last
> {{assignedAllocationID}}, if any.
> However, since the execution history is bounded (to, by default, 16 entries)
> this can lead this information being evicted.
> In other words, with the default configuration (history limit = 16, restart
> delay = 1s) local recovery can only kick if the TM is restarted within 16
> seconds.
> We should decouple this information from the execution (history).
