etcd vs Redis: What are the differences?
What is etcd? A distributed consistent key-value store for shared configuration and service discovery. etcd is a distributed key value store that provides a reliable way to store data across a cluster of machines. It’s open-source and available on GitHub. etcd gracefully handles master elections during network partitions and will tolerate machine failure, including the master.
What is Redis? An in-memory database that persists on disk. Redis is an open source, BSD licensed, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets.
etcd and Redis are primarily classified as "Open Source Service Discovery" and "In-Memory Databases" tools respectively.
"Service discovery" is the top reason why over 7 developers like etcd, while over 842 developers mention "Performance" as the leading cause for choosing Redis.
etcd and Redis are both open source tools. It seems that Redis with 37.4K GitHub stars and 14.4K forks on GitHub has more adoption than etcd with 25.9K GitHub stars and 5.26K GitHub forks.
According to the StackShare community, Redis has a broader approval, being mentioned in 3265 company stacks & 1788 developers stacks; compared to etcd, which is listed in 27 company stacks and 11 developer stacks.
