## What it is
Bitcask is a log-structured hash table storage engine for fast key/value data, written in Erlang by Basho. It is the underlying storage engine used by the Riak distributed database.

## Use cases
- embed a fast key/value storage engine in an Erlang application
- store key/value data with low write latency
- understand or reuse the storage engine behind Riak
- persist large numbers of keys with in-memory index lookups
- build a simple persistent hashmap on disk

## When to choose
- you are building Erlang/Elixir software that needs an embedded log-structured key/value store
- you need the exact storage engine used by Riak
- your workload is write-heavy with point lookups by key

## When to avoid
- you need a standalone database server rather than an embedded library
- you need range queries or secondary indexes, which bitcask does not support
- you need a storage engine with an active community and modern language bindings

## Facets
- artifact type: library
- maturity: maintenance
- function: database, caching
- domain: databases, developer-tools
- platform: elixir
- tags: key-value-store, storage-engine, log-structured, erlang, riak, linux, macos
