-------------------------------------
Summary: Checkpoint Race Condition in KuduSourceEnumerator
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
Fix For: 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.
