[jira] [Created] (SPARK-50845) Bound StateSchemaV3 files by performing full rewrite with latest schema

Eric Marnadi created SPARK-50845:
------------------------------------

             Summary: Bound StateSchemaV3 files by performing full rewrite with latest schema
                 Key: SPARK-50845
                 URL: https://issues.apache.org/jira/browse/SPARK-50845
             Project: Spark
          Issue Type: New Feature
          Components: Structured Streaming
    Affects Versions: 4.0.0
            Reporter: Eric Marnadi


Basically, whenever we evolve the schema, we write a new StateSchemaV3 file for a given operator. Currently, we bound the number of schema evolutions that can take place. In order to 'unbound' this, we want to perform a full-rewrite using the latest schema
