## What it is
Bedrock is a distributed database server built by Expensify on top of SQLite, providing WAN replication, active/active automatic failover, and a private blockchain for cluster synchronization. It is modular with plugins for databases, job queues, and caches, serving as a data foundation for global-scale applications.

## Use cases
- run a mysql alternative with wan replication across datacenters
- set up active/active database failover between regions
- build a globally distributed backend on sqlite
- replace mysql replication with a simpler distributed database
- run a job queue and cache backed by the same datastore
- deploy a geo-redundant database for a global-scale web service

## When to choose
- you need multi-datacenter WAN replication with automatic failover
- you want SQLite performance with networked, distributed transactions
- you prefer few configuration knobs with sensible defaults
- you want database, cache, and job queue in one platform

## When to avoid
- you need a widely supported database with a large ecosystem of drivers and tools
- you require complex SQL features or stored procedures beyond SQLite's capabilities
- you need multi-master write conflict resolution with rich data types
- your team cannot operate a less mainstream database

## Facets
- artifact type: service
- maturity: active
- function: database, caching, message-queue, rpc, security
- domain: databases, microservices, backend, self-hosted
- platform: cpp, c, self-hosted
- tags: sqlite, wan-replication, active-active, failover, distributed-transactions, mysql-alternative, plugins, linux, macos, web-server
