CrateIO vs Riak: What are the differences?
CrateIO: The Distributed Database for Docker. Crate is a distributed data store. Simply install Crate directly on your application servers and make the big centralized database a thing of the past. Crate takes care of synchronization, sharding, scaling, and replication even for mammoth data sets; Riak: A distributed, decentralized data storage system. Riak is a distributed database designed to deliver maximum data availability by distributing data across multiple servers. As long as your client can reach one Riak server, it should be able to write data. In most failure scenarios, the data you want to read should be available, although it may not be the most up-to-date version of that data.
CrateIO and Riak can be categorized as "Databases" tools.
"Simplicity" is the primary reason why developers consider CrateIO over the competitors, whereas "High Performance " was stated as the key factor in picking Riak.
CrateIO and Riak are both open source tools. It seems that Riak with 3.24K GitHub stars and 530 forks on GitHub has more adoption than CrateIO with 2.49K GitHub stars and 333 GitHub forks.
