Tarantool is an in-memory computing platform combining a fast NoSQL database with a Lua application server. It stores data in RAM with WAL persistence and LSM-tree support, and lets you run application logic next to the data.

Use cases

• replace a database plus cache with a single in-memory store
• build high-throughput message queues
• run stateful web application logic close to the data
• set up replicated, fault-tolerant data clusters
• use as an OLTP store faster than a relational database
• store and query documents with JSON path indexes

When to choose

• you need microsecond-latency reads and writes on data that fits in RAM
• you want to co-locate application code with the database to eliminate network hops
• you need built-in replication, sharding, and leader election
• you want a LuaJIT-based server with non-blocking cooperative multitasking

When to avoid

• your dataset is much larger than available RAM and you need a disk-first engine
• you rely heavily on complex SQL analytics better served by a relational database
• you need a managed cloud database service
• your team has no Lua experience and cannot adopt it
