## What it is
A MySQL-compatible SQL engine and server written in Go that runs queries over arbitrary data sources using the MySQL dialect and wire protocol. It ships with an in-memory database backend suitable for tests and lets you implement custom backends to query your own data sources.

## Use cases
- run a MySQL-compatible database in Go tests without installing MySQL
- query arbitrary data sources with SQL by implementing a custom backend
- drop-in replacement for MySQL for Go applications
- serve SQL over the MySQL wire protocol from a Go service
- test SQL queries in CI with an in-memory database

## When to choose
- you need MySQL wire-protocol compatibility in a Go project
- you want to expose non-database data sources via SQL
- you need an embeddable in-memory SQL engine for testing

## When to avoid
- you need a production-grade persistent database (use Dolt or MySQL itself)
- you need full MySQL feature parity including every edge-case behavior
- you cannot use Cgo or install ICU dependencies and need ICU regex support

## Facets
- artifact type: library
- maturity: active
- function: database, database-driver, http-server
- domain: databases, developer-tools, backend, apis
- platform: go, cross-platform
- tags: mysql-compatible, sql-engine, query-engine, wire-protocol, in-memory-database, storage-agnostic
