What is Apache Storm?

Apache Storm is famous for its unprecedented speed. It has clocked over a million tuples processed per second per node, which makes it considerably faster than Apache Spark.

Apache Storm focuses on scalability, fault-tolerance, and guarantees that your data will be processed. Apache is easy to set up and operate and can be used with any programming language.

Uses

Apache Storm has many use cases:

• real-time analytics
• online machine learning
• continuous computation
• distributed RPC
• Extract, transform, load (ETL)
• and more

Topology

Apache Storm reads a raw stream of real-time data from one end through a “spout.” The spout converts the input into a stream of tuples. This stream then passes through a sequence of small processing units called “bolts,” which output the other end’s processed information.
