query, either by query.stop()
or by an exception.
Waits for the termination of this
query, either by query.stop()
or by an exception.
If the query has terminated with an exception, then the exception will be thrown.
Otherwise, it returns whether the query has terminated or not within the timeoutMs
milliseconds.
If the query has terminated, then all subsequent calls to this method will either return
true
immediately (if the query was terminated by stop()
), or throw the exception
immediately (if the query has terminated with exception).

Blocks until all available data in the source has been processed and committed to the sink.
Blocks until all available data in the source has been processed and committed to the sink.
This method is intended for testing. Note that in the case of continually arriving data, this
method may block forever. Additionally, this method is only guaranteed to block until data that
has been synchronously appended data to a org.apache.spark.sql.execution.streaming.Source
prior to invocation. (i.e. getOffset
must immediately reflect the addition).
