MemSQL 6.5: NewSQL with autonomous workload optimization, improved data ingestion and query execution speed

Even though it's just naming conventions, MemSQL is usually thought of as part of the NewSQL lot. That is, databases grounded on the relational SQL model yet adopting some of the "knobs" the NoSQL lot has introduced for people to turn in order to achieve horizontal scalability. It's a balancing act between consistency and performance, which, in the end, applies to any distributed database. NewSQL folks argue you should not have to ditch schema, or SQL, to get the scale-out benefits that NoSQL brings. If you like your schema and SQL, and also like your database to have analytics as well as transactional capabilities, then MemSQL is probably in your radar.
