What changes were proposed in this pull request?
Follow-up to apache#48401. This PR enables Avro encoding for MapState and the PrefixKeyScanStateEncoder
Why are the changes needed?
UnsafeRow is an inherently unstable format that makes no guarantees of being backwards-compatible. Therefore, if the format changes between Spark releases, this could cause StateStore corruptions. Avro is more stable, and inherently enables schema evolution.
Does this PR introduce any user-facing change?
No
How was this patch tested?
Amended and added to unit tests
Was this patch authored or co-authored using generative AI tooling?
No
