Why are we getting Streams in Redis?

Redis has introduced a new data type called Streams, which offers advanced functionality compared to existing Redis structures like Pub/Sub and blocking lists. Streams are designed to handle complex data structures with key-value pairs, providing enhanced control and the ability to store messages persistently, unlike the ephemeral nature of Pub/Sub. They support operations like XADD for publishing and XREAD for consuming messages, with features akin to log file inspection, including blocking reads. Streams also introduce consumer groups, allowing messages to be processed by multiple consumers at varying speeds, with the added capability for consumers to acknowledge message receipt, ensuring reliable message processing. This new feature aims to expand Redis's utility in building scalable and robust messaging systems.
