Introduction to Redis Streams. Redis 5.0 is out, introducing the first new Redis data type in several years: streams, a Kafka-like mechanism for implementing a replayable event stream that can be read by many different subscribers. # 18th October 2018, 8:35 am
Mozilla Telemetry: In-depth Data Pipeline (via) Detailed behind-the-scenes look at an extremely sophisticated big data telemetry processing system built using open source tools. Some of this is unsurprising (S3 for storage, Spark and Kafka for streams) but the details are fascinating. They use a custom nginx module for the ingestion endpoint and have a “tee” server written in Lua and OpenResty which lets them route some traffic to alternative backend. # 12th April 2018, 3:44 pm
Redis streams aren’t exciting for their innovativeness, but rather than they bring building a unified log architecture within reach of a small and/or inexpensive app. Kafka is infamously difficult to configure and get running, and is expensive to operate once you do. [...] Redis on the other hand is probably already in your stack.
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! # 3rd October 2017, 3:25 pm
