[jira] [Created] (SPARK-34270) Combine StateStoreMetrics should not override individual StateStoreCustomMetric

L. C. Hsieh created SPARK-34270:
-----------------------------------

             Summary: Combine StateStoreMetrics should not override individual StateStoreCustomMetric
                 Key: SPARK-34270
                 URL: https://issues.apache.org/jira/browse/SPARK-34270
             Project: Spark
          Issue Type: Bug
          Components: Structured Streaming
    Affects Versions: 3.2.0
            Reporter: L. C. Hsieh
            Assignee: L. C. Hsieh


For stateful join in structured streaming, we need to combine StateStoreMetrics from both left and right side. Currently we simply take arbitrary one from custom metrics with same name from left and right. By doing this we miss half of metric number.
