> Moving Avro files to sql/core so they can be used by TransformWithState
> operator
> --------------------------------------------------------------------------------
>
> Key: SPARK-50112
> URL: https://issues.apache.org/jira/browse/SPARK-50112
> Project: Spark
> Issue Type: New Feature
> Components: Structured Streaming
> Affects Versions: 4.0.0
> Reporter: Eric Marnadi
> Assignee: Eric Marnadi
> Priority: Major
> Labels: pull-request-available
>
> With the introduction of the TransformWithState operator, we are going to
> persist all state information in the StateStore with Avro encoding, instead
> of UnsafeRow. This is because UnsafeRow is not backwards compatible and can
> change between Spark releases, potentially causing StateStore corruptions.
> Avro is backwards-compatible and can be reliably used. This change will move
> the necessary files to the sql/core directory so Avro encoding can be used by
> stateful streaming operators.
