Arvid Heise created FLINK-22682:
-----------------------------------
Summary: Checkpoint interval too large for higher DOP
Key: FLINK-22682
URL: https://issues.apache.org/jira/browse/FLINK-22682
Project: Flink
Issue Type: Bug
Components: Runtime / Checkpointing
Affects Versions: 1.14.0, 1.13.1
Reporter: Arvid Heise
When running a job on EMR with DOP of 160, checkpoints are not triggered at the
set interval. I used an interval of 10s and the average checkpoint took <10s,
so I'd expect ~6 checkpoints per minute.
However, the actual completion message was heavily delayed. I had backpressure
in this test.
