>             Project: Flink
>          Issue Type: Improvement
>          Components: API / DataStream
>    Affects Versions: 1.11.0

> 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?
