Fix Version/s: (was: 1.14.0)
1.15.0
> Support recovery (from checkpoints) after disabling changelog backend
> ---------------------------------------------------------------------
>
> Key: FLINK-23252
> URL: https://issues.apache.org/jira/browse/FLINK-23252
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / State Backends
> Reporter: Roman Khachatryan
> Priority: Major
> Fix For: 1.15.0
>
>
> Recovery from savepoint already works:
> * changelog off -> on: FLINK-23278
> * changelog on -> off: directly calling
> {{underlyingBackend.}}{{savepoint}}{{()}} (instead of {{writer.persist()}})
> For checkpoints, changelog on -> off doesn't work. Regular state backend will
> receive materialized and non-aterialized state on recovery. To support it,
> state changes have to be applied on recovery even if changelog backend is
> disabled.
