--------------------------------------
Summary: Passively timeout alignment on the inputs
Key: FLINK-19681
URL: https://issues.apache.org/jira/browse/FLINK-19681
Project: Flink
Issue Type: Sub-task
Components: Runtime / Checkpointing
Affects Versions: 1.12.0
Reporter: Piotr Nowojski
Assignee: Piotr Nowojski
Fix For: 1.12.0
CheckpointBarrierHandler will be aware of the aligned checkpoint barrier
announcement messages. Based on that, it can implement basic timeout. When
arriving aligned checkpoint barrier (or it's announcement) exceeded maximum
allowed `checkpointStartDelay`, it should switch to unaligned checkpoint.
This, for the time being could be done without registering any timeout action,
but a passive/static check when processing checkpoint barrier/barrier
announcement. If `checkpointStartDelay` is below threshold, do nothing. If
above, switch to unaligned checkpoint.
