When programming on Storm, you manipulate and transform streams of tuples, and a tuple is a named list of values. Tuples can contain objects of any type; if you want to use a type Storm doesn't know about it's <a href="/documentation/Serialization.html">very easy</a> to register a serializer for that type.</p> + +<p>There are just three abstractions in Storm: spouts, bolts, and topologies. A <strong>spout</strong> is a source of streams in a computation. Typically a spout reads from a queueing broker such as Kestrel, RabbitMQ, or Kafka, but a spout can also generate its own stream or read from somewhere like the Twitter streaming API. Spout implementations already exist for most queueing systems.</p> + +<p>A <strong>bolt</strong> processes any number of input streams and produces any number of new output streams. Most of the logic of a computation goes into bolts, such as functions, filters, streaming joins, streaming aggregations, talking to databases, and so on.</p> + +<p>A <strong>topology</strong> is a network of spouts and bolts, with each edge in the network representing a bolt subscribing to the output stream of some other spout or bolt. A topology is an arbitrarily complex multi-stage stream computation. Topologies run indefinitely when deployed.</p> + +<p>Storm has a "local mode" where a Storm cluster is simulated in-process. This is useful for development and testing. The "storm" command line client is used when ready to submit a topology for execution on an actual cluster.</p> + +<p>The <a href="https://github.com/apache/storm/tree/master/examples/storm-starter";>storm-starter</a> project contains example topologies for learning the basics of Storm.
