Introducing RedisRaft, a New Strong-Consistency Deployment Option - Redis
RedisRaftÂ (under development) is a new module for open source Redis that makes it possible to operate a number of Redis servers as a single fault-tolerant, strongly consistent cluster. As its name suggests, it is based on the Raft consensus algorithm and an open-source C library that implements it. RedisRaft brings a new strong-consistency with strict serializationÂ deployment option to Redis and t

Streams: a new general purpose data structure in Redis. - <antirez>
Until a few months ago, for me streams were no more than an interesting and relatively straightforward concept in the context of messaging. After Kafka popularized the concept, I mostly investigated their usefulness in the case of Disque, a message queue that is now headed to be translated into a Redis 4.2 module. Later I decided that Disque was all about AP messaging, which is, fault tolerance an

It accomplishes something that is almost illogical given how little it asks for in terms of time or space. This algorithm is called HyperLogLog, and today it is introduced as a new data structure for Redis. Co
