Answer / Vickey Saxena
The Apache Storm codebase has three main layers:
1. API Layer: It provides a high-level programming interface for developers to create topologies and define bolts and spouts. This layer includes APIs for Java, Python, Ruby, Clojure, and Scala.
2. Core Execution Engine (Cog): It is responsible for scheduling and executing the topology and managing resources across the cluster.
3. Transport Layer: It manages communication between the various nodes in a Storm cluster using messaging queues like Kafka, RabbitMQ, or Redis.
