> Make CompletedCheckpointStore backwards compatible?
> ---------------------------------------------------
>
> Key: FLINK-13692
> URL: https://issues.apache.org/jira/browse/FLINK-13692
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Checkpointing
> Affects Versions: 1.9.0, 1.10.0
> Reporter: Till Rohrmann
> Priority: Major
> Fix For: 1.10.0, 1.9.1
>
>
> With FLINK-11159 we changed the signature of
> {{CompletedCheckpointStore#getLatestCheckpoint}} from
> {{getLatestCheckpoint()}} to {{getLatestCheckpoint(boolean)}}. This is an API
> breaking change which causes users of this interface having to adapt their
> implementation and recompile it. Since {{CompletedCheckpointStore}} is no
> public API, this change is technically ok, but not so nice.
> If we decide to provide backwards compatibility, then we should still keep
> {{getLatestCheckpoint()}} and add a deprecation annotation to it. At least,
> we should update the JavaDocs of the
> {{CompletedCheckpointStore#getLatestCheckpoint}} method to reflect what the
> passed parameter states.
