I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help
the community manage its development. I see this issue is assigned but has not
received an update in 14, so it has been labeled "stale-assigned".
If you are still working on the issue, please remove the label and add a
comment updating the community on your progress. If this issue is waiting on
feedback, please consider this a reminder to the committer/reviewer. Flink is a
very active project, and so we appreciate your patience.
If you are no longer working on the issue, please unassign yourself so someone
else may work on it. If the "warning_label" label is not removed in 7 days, the
issue will be automatically unassigned.
> Update state reader to return InputFormat
> -----------------------------------------
>
> Key: FLINK-21341
> URL: https://issues.apache.org/jira/browse/FLINK-21341
> Project: Flink
> Issue Type: Improvement
> Components: API / State Processor
> Affects Versions: 1.13.0
> Reporter: Seth Wiesman
> Assignee: Jun Qin
> Priority: Major
> Labels: auto-unassigned, stale-assigned
>
> The state processor api on read currently takes an ExecutionEnvironment and
> returns a DataSet. As Flink now supports Bounded DataStream we want to
> support that as well but not have to maintain parallel apis. To that end we
> propose the following.
> Introduce a new `load` method to Savepoint.
>
> {code:java}
> SavepointReader Savepoint#load(String path, StateBackend backend);
> {code}
> SavepointReader will contain the same read methods as ExistingSavepoint but
> they will instead return InputFormat<T, ?>. This way the input format can be
> used with either DataSet, DataStream, or Table API.
>
> The reader methods in ExistingSavepoint should be deprecated.
>
> Additionally, OperatorStateInputFormat and KeyedStateInputFormat should both
> now extend ResultTypeQueryable so users get efficient serializer for their
> reads.
