> Limit the number of StreamingQueryListener.StreamProgressEvent when there is 
> no data

>                 Key: SPARK-18670
>                 URL: https://issues.apache.org/jira/browse/SPARK-18670
>             Project: Spark
>          Issue Type: Bug
>          Components: Structured Streaming
>            Reporter: Tathagata Das
>            Assignee: Shixiong Zhu
>            Priority: Critical
> When a StreamingQuery is not receiving any data, and no processing trigger is 
> set, it attempts to run a trigger every 10 ms. This would generate 
> StreamingQueryListener events at a very high rate. This should be limited 
> such that as long as data is not being received, it should generate events 
> once every X seconds.
