             Summary: Cache out-of-order streaming ReadBlock responses instead of discarding them to avoid client poll timeout
                 Key: HDDS-16208
                 URL: https://issues.apache.org/jira/browse/HDDS-16208
             Project: Apache Ozone
          Issue Type: Sub-task
          Components: Ozone Client
    Affects Versions: 2.3.0
            Reporter: Sergey Soldatov
            Assignee: Sergey Soldatov


Streaming read responses can arrive out of order because the datanode serves pre-read requests on concurrent chunk reader threads. When a response arrives ahead of the current read position, the client drops it and never re-requests that range, so the read eventually fails with a poll timeout (default 10s).
