What is Spark Streaming in Spark?

Spark Streaming is a component used for real-time data processing that allows us to perform real-time stream processing on Spark. It offers advanced abstractions for processing real-time data streams, enabling data to be read from various sources such as Kafka, Flume, Kinesis, and then transformed, processed, and outputted. Spark Streaming processes data in a micro-batch manner, dividing continuous data streams into smaller batches and processing each batch. This enables low-latency real-time processing with fault tolerance and scalability. Spark Streaming provides a rich API and features that make it easy for developers to build complex real-time stream processing applications.
