First, Introduction This blog post shows you how to build a Redis-based distributed lock step at a pace. Will start with the most original version, then adjust according to the problem, and finally complete a more reasonable distributed lock. This article divides the implementation of the distributed lock into two parts, one is the single-machine environment and the other is the Redis lock implementation i

queues as an embedded list to meet real-time high concurrency requirements. In the process of processing data of an e-commerce type, queues related to commodities, hot sales, and recommended sorting are usually stored in redis, during which storm is also expanded to read and update the redis list.

Redis is a high-performance key-value database. Its key has a wide range of data structures: string, hash, list set, and sorted set. Compared with memcache, NOSQL not only has a rich key data structure, but also has persistence functions. It also supports master-slave replication, making it easy to build clusters. Redis's high performance is largely derived from its memory-type database, which features a set operation of 11 w/s and a get operation of
