In-memory computing platform

Tarantool is an integration of a Lua application server and a database management system. The DBMS was originally developed as an in-memory NoSQL DBMS, and later it was extended with a disk storage engine option. Now it is positioned as in-memory computing platform. Tarantool's in-memory engine is lock-free. It uses cooperative multitasking to handle thousands of connections simultaneously. There is a fixed number of independent execution threads and they do not share state. The disk-based storage engine also exploits the advantage of single-threaded requests and hence avoid unnecessary synchronization overhead. Tarantool also supports secondary indexes, asynchronous replication, and some SQL operations.
