Chaoqin Li updated SPARK-45747:
-------------------------------
Summary: Support session window aggregation in state reader (was: Support
session window operator in state reader)
> Support session window aggregation in state reader
> --------------------------------------------------
>
> Key: SPARK-45747
> URL: https://issues.apache.org/jira/browse/SPARK-45747
> Project: Spark
> Issue Type: Improvement
> Components: Structured Streaming
> Affects Versions: 3.5.0
> Reporter: Chaoqin Li
> Priority: Major
>
> We are introducing state reader in SPARK-45511, but currently session window
> operator is not supported because the numColPrefixKey is unknown. We can read
> the operator state metadata introduced in SPARK-45558 to determine the number
> of prefix columns and load the state of session window correctly.
