At its core, Storm works by processing data in real-time through a concept known as "topologies." A topology in Storm is essentially a data flow graph that defines how data is processed. It consists of spouts (the sources of data) and bolts (the processing units). Spouts emit data into the topology, and bolts process that data, potentially emitting new data streams to other bolts for further processing. This flexible architecture allows for complex data processing pipelines to be built and scaled as necessary.

: The primary coordinator daemon. Nimbus is responsible for uploading code, assigning execution tasks to specific worker machines, and tracking cluster performance. If a worker drops offline, Nimbus identifies the failure and reassigns the workload.

Apache Storm has long been the backbone of real-time data processing, doing for live streams what Hadoop did for batch processing. With the release of the 2.6.0 series

Upgraded Netty, the underlying networking framework, ensuring faster and more stable data transfer between workers.
