ClustrixDB vs TokuMX: What are the differences?
Developers describe ClustrixDB as "Clustered SQL database built for e-commerce". ClustrixDB is a scale-out SQL database built from the ground up with a distributed shared nothing architecture, automatic data redistribution (so you never need to shard), with built in fault tolerance, all accessible by a simple SQL interface and support for business critical MySQL features – replication, triggers, stored routines, etc. On the other hand, TokuMX is detailed as "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.
ClustrixDB and TokuMX belong to "Databases" category of the tech stack.
