[jira] [Created] (FLINK-13955) Integrate ContinuousFileReaderOperator with StreamTask mailbox execution model

Alex created FLINK-13955:
----------------------------

             Summary: Integrate ContinuousFileReaderOperator with StreamTask mailbox execution model
                 Key: FLINK-13955
                 URL: https://issues.apache.org/jira/browse/FLINK-13955
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Task
            Reporter: Alex


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, preventing progress in mailbox loop.

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