Tarantool is an in-memory database and application server.
Tarantool can be used in OLTP scenarios instead of relational databases, and such a solution will work many times faster. With Tarantool, you can replace the traditional bundle of database & cache and benefit from that by reducing operational costs.
It’s is tolerant to write-heavy load. Also, you will be able to keep full-featured applications next to the data thus reducing the data access network latency to zero.
The software is free and open source software.
Features of the application server include:
- 100% compatible drop-in replacement for Lua 5.1, based on LuaJIT 2.1. Simply use #!/usr/bin/tarantool instead of #!/usr/bin/lua in your script.
- Full support for Lua modules and a rich set of own modules, including cooperative multitasking, non-blocking I/O, access to external databases, etc
Features of the database include:
- ANSI SQL, including views, joins, referential and check constraints.
- MsgPack data format and MsgPack based client-server protocol.
- Two data engines: 100% in-memory with optional persistence and an own implementation of LSM-tree, to use with large data sets.
- Multiple index types: HASH, TREE, RTREE, BITSET.
- Asynchronous master-master replication.
- Authentication and access control.
- The database is just a C extension to the application server and can be turned off.
