CrateIO vs TokuMX: 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; TokuMX: A high-performance, concurrent, compressing, drop-in replacement engine for MongoDB. TokuMX is a drop-in replacement for MongoDB, and offers 20X performance improvements, 90% reduction in database size, and support for ACID transactions with MVCC. TokuMX has the same binaries, supports the same drivers, data model, and features of MongoDB, because it shares much of its code with MongoDB.

CrateIO and TokuMX can be categorized as "Databases" tools.

"Simplicity" is the primary reason why developers consider CrateIO over the competitors, whereas "When your two-week MongoDB love affair ends, try this" was stated as the key factor in picking TokuMX.

CrateIO and TokuMX are both open source tools. CrateIO with 2.49K GitHub stars and 333 forks on GitHub appears to be more popular than TokuMX with 679 GitHub stars and 90 GitHub forks.
