Redis 8.2 streams and bitmap enhancements

Redis 8.2 introduces significant enhancements to its streams and bitmap functionalities, addressing challenges commonly faced by developers. The update includes two new commands, XACKDEL and XDELEX, which simplify the management of Redis Streams by allowing more efficient message acknowledgment and deletion processes within multi-consumer groups. These commands offer options like KEEPREF, DELREF, and ACKED to control how entries are deleted from streams and consumer groups' Pending Entries Lists (PELs). Additionally, Redis 8.2 expands the BITOP command with four new logical operators—DIFF, DIFF1, ANDOR, and ONE—enabling more complex set operations with bitmaps, which are often used for storing individual properties in applications like gaming and adtech. These enhancements aim to streamline operations and enhance the functionality of applications built with Redis, with the new tools being available immediately for users to download and implement.
