[jira] [Created] (FLINK-28826) Avoid notifying too frequently when recycling buffers for BatchShuffleReadBufferPool

Yuxin Tan created FLINK-28826:
---------------------------------

             Summary: Avoid notifying too frequently when recycling buffers for BatchShuffleReadBufferPool
                 Key: FLINK-28826
                 URL: https://issues.apache.org/jira/browse/FLINK-28826
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Network
    Affects Versions: 1.16.0
            Reporter: Yuxin Tan


When recycling buffers in BatchShuffleReadBufferPool, the number of buffers may be larger than numBuffersPerRequest, which may cause too frequent notifications that the buffers are already available.

So we should modify the condition of notifications that the buffer is available to solve this problem.
