What is the primary role of a "source" in an Apache Beam pipeline?
To filter data before it enters the pipeline.
To read input data into the pipeline.
To write output data from the pipeline.
To rebalance work dynamically within the pipeline.
What is a "bounded source" in Apache Beam typically associated with?
Streaming data processing.
Batch data processing.
Real-time data analysis
Unstructured data handling.
How does Apache Beam ensure that already processed data in a stream doesn't need to be re-read when using an unbounded source?
By dynamically rebalancing work across workers.
By using checkpoints to bookmark the data that has been read.
By splitting the input into smaller bundles.
By discarding data that has already been seen.
What function does the record ID serve in unbounded sources like PubSub IO in Apache Beam?
It helps in dynamically rebalancing the workload.
It allows deduplication of messages to prevent processing duplicates.
It determines the processing time of each message.
It specifies the destination for output data.
What is the significance of a PDone value in an Apache Beam pipeline?
It signals that a PTransform has started.
It indicates that a source has finished reading all its input data.
It signifies the completion of a transform, typically a sink.
It marks the point where the pipeline has been dynamically rebalanced.
