-----------------------------------
Summary: Introduce UnsafeRow format validation for streaming state
store
Key: SPARK-31894
URL: https://issues.apache.org/jira/browse/SPARK-31894
Project: Spark
Issue Type: Bug
Components: Structured Streaming
Affects Versions: 3.1.0
Reporter: Yuanjian Li
Currently, Structured Streaming directly puts the UnsafeRow into StateStore
without any schema validation. It's a dangerous behavior when users reusing the
checkpoint file during migration. Any changes or bug fix related to the
aggregate function may cause random exceptions, even the wrong answer, e.g
SPARK-28067.
Here we introduce an UnsafeRow format validation for the state store.
