[jira] [Created] (FLINK-28635) HybridSourceReader availabilityFuture always completed

hongfei zhang created FLINK-28635:
-------------------------------------

             Summary: HybridSourceReader availabilityFuture always completed
                 Key: FLINK-28635
                 URL: https://issues.apache.org/jira/browse/FLINK-28635
             Project: Flink
          Issue Type: Bug
          Components: Connectors / Common
    Affects Versions: 1.15.1, 1.15.0
            Reporter: hongfei zhang


HybridSourceReader may contains multi SourceReader.

AvailabilityFuture is variable in some reader like kafka, but AvailabilityFuture  is not always changing in HybridSourceReader.

This leads to a problem: 
 * task busy time is calculated based on idle time
 * idle time is based on operator AvailabilityFuture
 * When the idle time is constant, it will always be busy
