Streams: a new general purpose data structure in Redis. Exciting new Redis feature inspired by Kafka: redis streams, which allow you to construct an efficient, in-memory list of messages (similar to a Kafka log) which clients can read sections of or block against and await real-time delivery of new messages. As expected from Salvatore the API design is clean, obvious and covers a wide range of exciting use-cases. Planned for release with Redis 4 by the end of the year!
