This document discusses using RabbitMQ and Java workers to provide atomic and idempotent counters in Cassandra. The workers consume messages from RabbitMQ queues, perform in-memory atomic counter operations, persist to Cassandra, and push static counter values to Cassandra periodically. This allows real-time analytics, fast operations, atomicity through single-threaded workers, and graceful recovery if a worker crashes through the persisted static counter values. The approach supports over 1 million operations per second per worker and requires sharding data at the application layer for scalability beyond a single worker.
