- case class ContinuousQueryInfo(

 }

+ private def toInfo: ContinuousQueryInfo = {


Do we need to make this a deep copy, especially for sourceStatuses and sinkStatus ?

No. They are immutable.

+ * A class that contains information about [[ContinuousQuery]].
+ */
+@Experimental
+case class ContinuousQueryInfo(


We should scaladoc these parameters.

We also probably don't want this to be a case class. The issue is that if we add new parameters in the future, the unapply method will break binary compatibility. The constructor should also be private.

Removed case.

The exception is not tested.

Added a test for the exception

Can you include the json produced as a sanity check?

I reverted c24b6b6 as there is a Option serialization bug in jackson-module-scala 2.7.3 (FasterXML/jackson-module-scala#240)

zsxwing · 2016-05-30T05:40:41Z

Change the type to Array as jackson-module-scala doesn't support Seq[Option[X]]. Probably because of the type erasure.

+case class WrappedContinuousQueryListenerEvent(


Move it out of ContinuousQueryListenerBus in order to eliminate the reference

I don't actually understand the structure of all the different even busses, but why do we need a different event type? Why don't all the events just extend SparkListenerEvent?

Good point. This pattern is from the Streaming events. But that's for binary compatibility. We don't need this pattern in the new APIs.

 class SourceStatus private[sql] (
 val description: String,
- val offset: Option[Offset])
+ val offset: Option[String])


offset --> offsetDesc, so that it allows us in future to expose actual offsets without the naming being weird.

+class ContinuousQueryInfo private[sql](

This should also probably be an Array. No need to be a Seq.

Offline discussion: this is okay. this is how it is for SparkListener, and avoid problems like the array being accidentally modified internally by the listener generator.

LGTM. Will merge after tests pass.
