Apache Samza is an open-source near-realtime, asynchronous computational framework for stream processing developed by the Apache Software Foundation in Scala and Java.

Samza allows you to build stateful applications that process data in real-time from multiple sources including Apache Kafka.

Samza provides fault tolerance, isolation and stateful processing. Unlike batch systems (like Hadoop or Spark) it provides continues computation and output, which result in sub-second[1] response times.

There are many players in the field of real time stream processing and Samza is one of the mature products[2][3][4] . It has been added to Apache in 2013[5].

Samza is used by multiple companies[6]. The biggest installation is in Linkedin.


Apache Samza has been developed in conjunction with Apache Kafka. Both were originally developed by LinkedIn.[7]
