----------------------------------
Summary: Support session window operator 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
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.
