Tarantool: Open-Source NoSQL Database and Application Server
An open-source database combining in-memory performance, Lua application server, task scheduling, and connectors for external databases and services.
What is Tarantool?
Tarantool is an open-source NoSQL database and application server designed for real-time applications that require high performance and scalability. Some key features of Tarantool:
- In-memory NoSQL database for fast data access and real-time performance. Supports key-value, documents, timeseries and message queues.
- Lua application server for storing application logic and procedures inside the database.
- Asynchronous event-driven architecture for high concurrency and throughput.
- ACID transactions for data consistency.
- Failover and replication for high availability.
- SQL support and connectors for integrating with external databases.
- Can be embedded into applications or run as a separate database server.
Tarantool is well-suited for real-time applications such as messaging, IoT, social networks, gaming, ad tech, fintech and geospatial. It's used by companies like Mail.Ru, CloudFlare, VK and Wikimedia Foundation. The in-memory architecture delivers microsecond response times and support for up to 500K TPS per node. Lua procedures allow complex data processing and task scheduling to be handled directly inside the database.
