Fast data ingest and processing is crucial for big data applications in fields like IoT, e-commerce, security, communications, entertainment, finance, and retail. Redis offers a solution to these challenges with its high performance, variety of data structures, and efficient message broker capabilities. It can handle over one million read/write operations per second with sub-millisecond latencies on commodity cloud instances. Redis' publish/subscribe feature allows it to act as an efficient message broker between geographically distributed data ingest nodes. For larger datasets, Redis Enterprise combines RAM and Flash memory for cost-effective performance at scale.
