spark streaming also relies on batching for micro-batching. The receiver divides the input data stream into short batches and processes micro batches in a similar way to spark jobs. Spark Streaming provides a high-level declarative API (support for Scala,java and Python).Samza was initially developed as a stream-processing solution for LinkedIn, and has been a k
