Integrate ContinuousFileReaderOperator with StreamTask mailbox execution model

    XMLWordPrintableJSON

    Details

      Description

      The ContinuousFileReaderOperator spawns an additional (reader) thread and coordinates actions with it via checkpointLock. The operator may block, waiting for a notification from the reader thread, potentially preventing progress in mailbox loop.

      This is similar to AsyncWaitOperator situation described in FLINK-12958.
