MemSQL is a next generation database that removes the most common bottleneck applications hit today: disk. By offering a familiar relational interface to an in-memory data tier, MemSQL empowers developers with the technology web-scale companies use to cope with massive traffic and growth. MemSQL offers orders of magnitude improvements in write and read performance and greatly simplifies application development and maintenance by offering wire-compatibility with MySQL.
It works like MySQL but more faster.
