trait ProgressReporter extends Logging

Responsible for continually reporting statistics about the amount of data processed as well as latency for a streaming query. This trait is designed to be mixed into the StreamExecution, who is responsible for calling startTrigger and finishTrigger at the appropriate times. Additionally, the status can updated with updateStatusMessage to allow reporting on the streams current state (i.e. "Fetching more data").

  10. def finishTrigger(hasNewData: Boolean, hasExecuted: Boolean): Unit

    Finalizes the query progress and adds it to list of recent status updates.

    Finalizes the query progress and adds it to list of recent status updates.

    hasNewData

    Whether the sources of this stream had new data for this trigger.

    hasExecuted

    Whether any batch was executed during this trigger. Streaming queries that perform stateful aggregations with timeouts can still run batches even though the sources don't have any new data.
