## What it is
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

## Facets
