## What it is
Riak is a decentralized, distributed NoSQL key-value datastore built in Erlang by Basho Technologies, designed for high availability and operational simplicity. The ecosystem includes Riak KV for general storage, Riak TS for IoT/time-series workloads, and Riak CS for S3-compatible object storage.

## Use cases
- store key-value data across a fault-tolerant distributed cluster
- run a highly available NoSQL database that survives node failures
- handle IoT time-series data at scale
- self-host an S3-compatible object store
- deploy a masterless database with no single point of failure

## When to choose
- you need masterless replication and tunable consistency across datacenters
- high availability and partition tolerance matter more than complex queries
- you want an Erlang-based distributed datastore with proven operational track record

## When to avoid
- you need rich ad-hoc queries, joins, or SQL
- your dataset is small enough for a single-node database
- you want a project with a large active community and frequent feature development

## Facets
- artifact type: application
- maturity: maintenance
- function: database, caching, object-storage
- domain: databases, microservices, big-data, iot
- platform: cross-platform, self-hosted
- tags: nosql, key-value-store, erlang, distributed-database, high-availability, time-series, s3-compatible, linux, macos
