> Add explicit method to StateChangelogWriter to write metadata
> -------------------------------------------------------------
>
> Key: FLINK-23035
> URL: https://issues.apache.org/jira/browse/FLINK-23035
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / State Backends
> Reporter: Roman Khachatryan
> Priority: Minor
> Fix For: 1.15.0
>
>
> Currently, metadata is written to the state changelog using the same
> StateChangelogWriter.append() method as data.
> However, it doesn't belong to a specific group, and should be read first on
> recovery. Because of that, -1 is used.
> An explicit append() without keygroup would be less fragile (probably still
> using -1 under the hood).
