Tarantool is an in-memory computing platform consisting of a database and an application server.

It is distributed under BSD 2-Clause terms.

Key features of the application server:

• Heavily optimized Lua interpreter with incredibly fast tracing JIT compiler, based on LuaJIT 2.1.
• Cooperative multitasking, non-blocking IO.
• Persistent queues.
• Sharding.
• Cluster and application management framework.
• Access to external databases such as MySQL and PostgreSQL.
• A rich set of built-in and standalone modules.

Key features of the database:

• MessagePack data format and MessagePack based client-server protocol.
• Two data engines: 100% in-memory with complete WAL-based persistence and an own implementation of LSM-tree, to use with large data sets.
• Multiple index types: HASH, TREE, RTREE, BITSET.
• Document oriented JSON path indexes.
• Asynchronous master-master replication.
• Synchronous quorum-based replication.
• RAFT-based automatic leader election for the single-leader configuration.
• Authentication and access control.
• ANSI SQL, including views, joins, referential and check constraints.
• Connectors for many programming languages.
• The database is a C extension of the application server and can be turned off.

Supported platforms are Linux (x86_64, aarch64), Mac OS X (x86_64, M1), FreeBSD (x86_64).

Tarantool is ideal for data-enriched components of scalable Web architecture: queue servers, caches, stateful Web applications.
