Moody A Amakobe. Stream processing is designed to analyze and act on real-time streaming data with the use of continuous queries It supports applications that generate data from multiple sources and are pushed asynchronously to processing servers.

Sakr and Gaber found that there has been considerable advancements in the area of stream processing in the last ten years. The stream processing solutions have advanced with the ability to distribute different queries among a cluster of nodes. This paper will compare Apache Samza and Storm specifying each systems technical features based by architecture, performance optimization and scalability.

Apache Samza Apache Samza was created by LinkedIn to address certain stream processing requirements in the company.

Its goal is to provide a lightweight framework for continuous data processing Ramesh, n. According to Apache n. Samza has the following features. When the processor is restarted, Samza restores its state to consistent snapshot.

Kafka guarantees that messages are processed in the order they were written to a partition.

Samza is partitioned and distributed at every level. Samza provides a pluggable API that runs on other environments. According to Siciliani , Apache Samza processes messages as they are received, one at a time. Streams are divided into partitions. The partitions are ordered sequences of read-only messages, each message contains a unique ID. The system also supports consuming several messages from the same stream partition in sequence, a process known as batching.

Samza is made up of three layers: Provides out of the box support for Kafka 2. Out of the box support for YARN 3.
