StreamExecution

class StreamExecution extends ContinuousQuery with Logging

Manages the execution of a streaming Spark SQL query that is occurring in a separate thread. Unlike a standard query, a streaming query executes repeatedly each time new data arrives at any Source present in the query plan. Whenever new data arrives, a QueryExecution is created and the results are committed transactionally to the given Sink.

    Blocks the current thread until processing for data from the given source has reached at least the given Offset.

    Blocks the current thread until processing for data from the given source has reached at least the given Offset. This method is indented for use primarily when writing tests.

  11. def awaitTermination(timeoutMs: Long): Boolean

    Waits for the termination of this 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 an 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).
