Storm is a distributed, real-time computational framework that makes processing unbounded streams of data easy.

Storm can be integrated with your existing queuing and persistence technologies, consuming streams of data and processing/transforming these streams in many ways.

Topology

A Storm topology is a graph of computation where the nodes represent some individual computations and the edges represent the data being passed between nodes. We then feed data into this graph of computation in order to achieve some goal.

Tuple

The nodes in our topology send data between one another in the form of tuples. A tuple…
