[jira] [Created] (FLINK-17878) StreamingFileWriter watermark attribute is transient, this might be different with origin value

xiaogang zhou created FLINK-17878:
-------------------------------------

             Summary: StreamingFileWriter watermark attribute is transient, this might be different with origin value
                 Key: FLINK-17878
                 URL: https://issues.apache.org/jira/browse/FLINK-17878
             Project: Flink
          Issue Type: Improvement
          Components: API / DataStream
    Affects Versions: 1.11.0
            Reporter: xiaogang zhou


StreamingFileWriter has a 

private transient long currentWatermark = Long.MIN_VALUE;

 

in case developer wants to create a custom bucket assigner, it will receive a currentWatermark as 0, this might be conflict with the original flink approach to handle a min_long.

 

should we remove the transient key word?
