Question #: 239
Topic #: 1

Which statement characterizes the general programming model used by Spark Structured Streaming?

A. Structured Streaming leverages the parallel processing of GPUs to achieve highly parallel data throughput. B. Structured Streaming is implemented as a messaging bus and is derived from Apache Kafka. C. Structured Streaming uses specialized hardware and I/O streams to achieve sub-second latency for data transfer. D. Structured Streaming models new data arriving in a data stream as new rows appended to an unbounded table. E. Structured Streaming relies on a distributed network of nodes that hold incremental state values for cached stages.

Suggested Answer: D Vote an answer

The key idea in Structured Streaming is to treat a live data stream as a table that is being continuously appended. This leads to a new stream processing model that is very similar to a batch processing model. You will express your streaming computation as standard batch-like query as on a static table, and Spark runs it as an incremental query on the unbounded input table. Let's understand this model in more detail.
