Labels: pull-request-available (was: )
> Optimize Flink checkpoint meta mechanism to fix mistaken pending instants
> -------------------------------------------------------------------------
>
> Key: HUDI-4287
> URL: https://issues.apache.org/jira/browse/HUDI-4287
> Project: Apache Hudi
> Issue Type: Bug
> Components: flink
> Reporter: Shizhi Chen
> Assignee: Shizhi Chen
> Priority: Blocker
> Labels: pull-request-available
> Fix For: 0.12.0
>
>
> CkpMetadata is introduced into flink module to reduce timeline burden, but
> currently its
> mechanism lacks corresponding status for rollback instants, which may result
> in commit/delta commit instants deletion, and thus
> StreamWriteOperatorCoordinator(meta end) and Write function(data end) will
> not be coordinatited correctly.
> Finally, data files will be deleted by mistake.
> This situation will be easy to reproduced especially when
> StreamWriteOperatorCoordinator schedules table services for a long time
> between commit and init instants after the restoring from a checkpoint.
