Jun Qin commented on FLINK-25920:
---------------------------------
Our customer also facing the same problem here with 1.15.1 + aligned checkpoint:
{code:bash}
Checkpointing Mode Exactly Once
Checkpoint Storage FileSystemCheckpointStorage
State Backend EmbeddedRocksDBStateBackend (also jobs with HashMapStateBackend)
Interval 5m 0s
Timeout 5m 0s
Minimum Pause Between Checkpoints 5m 0s
Maximum Concurrent Checkpoints 1
Unaligned Checkpoints Disabled
Persist Checkpoints Externally Enabled (retain on cancellation)
Tolerable Failed Checkpoints 5
Checkpoints With Finished Tasks Enabled
{code}
Is there a workaround we can use?
