             Summary: How to know a partition is ready when using Structured Streaming 
                 Key: SPARK-26636
                 URL: https://issues.apache.org/jira/browse/SPARK-26636
             Project: Spark
          Issue Type: Improvement
          Components: Structured Streaming
    Affects Versions: 2.3.2
            Reporter: Guo Wei


When using structured streaming, we use "partitionBy" api  to partition the output data, and use the watermark based on event-time to handle delay records, but how to tell downstream users  that a partition data is ready? For example, when to write an empty "hadoop.done" file in a paritition directory?
