>
> Key: FLINK-38575
> URL: https://issues.apache.org/jira/browse/FLINK-38575
> Project: Flink
> Issue Type: Improvement
> Components: Connectors / Kudu
> Affects Versions: 2.0.0
> Reporter: Marton Greber
> Priority: Major
> Fix For: kudu-2.1.0
>
>
> KuduSourceEnumerator violates Flink's documented CheckpointListener
> pattern[1] by mutating state immediately in handleSourceEvent() instead of
> deferring until notifyCheckpointComplete(). This creates a race condition
> where splits are removed from state before records are durable, causing data
> loss on crash.
