Redis vs RethinkDB: What are the differences?

Developers describe Redis as "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. On the other hand, RethinkDB is detailed as "JSON. Scales to multiple machines with very little effort. Open source". RethinkDB is built to store JSON documents, and scale to multiple machines with very little effort. It has a pleasant query language that supports really useful queries like table joins and group by, and is easy to setup and learn.

Redis belongs to "In-Memory Databases" category of the tech stack, while RethinkDB can be primarily classified under "Databases".

"Performance" is the top reason why over 842 developers like Redis, while over 46 developers mention "Powerful query language" as the leading cause for choosing RethinkDB.

Redis and RethinkDB are both open source tools. Redis with 37.1K GitHub stars and 14.3K forks on GitHub appears to be more popular than RethinkDB with 22.3K GitHub stars and 1.73K GitHub forks.

reddit, Instacart, and Slack are some of the popular companies that use Redis, whereas RethinkDB is used by miDrive, Runbook, and The Control Group. Redis has a broader approval, being mentioned in 3239 company stacks & 1732 developers stacks; compared to RethinkDB, which is listed in 37 company stacks and 25 developer stacks.

    What are some alternatives to Redis and RethinkDB?
    Memcached
    Memcached is an in-memory key-value store for small chunks of arbitrary data (strings, objects) from results of database calls, API calls, or page rendering.
    MongoDB
    MongoDB stores data in JSON-like documents that can vary in structure, offering a dynamic, flexible schema. MongoDB was also designed for high availability and scalability, with built-in replication and auto-sharding.
    RabbitMQ
    RabbitMQ gives your applications a common platform to send and receive messages, and your messages a safe place to live until received.
    Hazelcast
    With its various distributed data structures, distributed caching capabilities, elastic nature, memcache support, integration with Spring and Hibernate and more importantly with so many happy users, Hazelcast is feature-rich, enterprise-ready and developer-friendly in-memory data grid solution.
    Cassandra
    Partitioning means that Cassandra can distribute your data across multiple machines in an application-transparent matter. Cassandra will automatically repartition as machines are added and removed from the cluster. Row store means that like relational databases, Cassandra organizes data by rows and columns. The Cassandra Query Language (CQL) is a close relative of SQL.
