# mysql-es > A MySql implementation of the `PersistedEventRepository` trait in cqrs-es. --- ## Usage Add to your Cargo.toml file: ```toml [dependencies] cqrs-es = "0.4.12" mysql-es = "0.4.12" ``` Requires access to a MySql DB with existing tables. See: - [Sample database configuration](db/init.sql) - Use `docker-compose` to quickly setup [a local database](docker-compose.yml) A simple configuration example: ``` let store = default_mysql_pool("mysql://my_user:my_pass@localhost:3306/my_db"); let cqrs = mysql_es::mysql_cqrs(pool, vec![]) ``` Things that could be helpful: - [User guide](https://doc.rust-cqrs.org) along with an introduction to CQRS and event sourcing. - [Demo application](https://github.com/serverlesstechnology/cqrs-demo) using the warp http server. - [Change log](https://github.com/serverlesstechnology/cqrs/blob/main/docs/versions/change_log.md) ## Runtime and TLS configuration This package defaults to expect the [Tokio runtime](https://crates.io/crates/tokio) and the [Rustls library](https://crates.io/crates/rustls) for TLS. If a different combination is desired the appropriate feature flag should be used: - `runtime-tokio-native-tls` - `runtime-tokio-rustls` (default) - `runtime-async-std-native-tls` - `runtime-async-std-rustls` - `runtime-actix-native-tls` - `runtime-actix-rustls` [![Crates.io](https://img.shields.io/crates/v/mysql-es)](https://crates.io/crates/mysql-es) [![docs](https://img.shields.io/badge/API-docs-blue.svg)](https://docs.rs/mysql-es) ![docs](https://codebuild.us-west-2.amazonaws.com/badges?uuid=eyJlbmNyeXB0ZWREYXRhIjoiRTZsVnY1emVCV1JXblVOMHpZTHdoS3JuVVVOUmRRb054Z2dYZmhKMk9PVU1zYklUaUhOTkM1d3l1czRWQUhBa28yWHM0RmRacmE3SWRmT1pJVU83akFVPSIsIml2UGFyYW1ldGVyU3BlYyI6InNuZ3U4MVBGYUFNbmhmLzIiLCJtYXRlcmlhbFNldFNlcmlhbCI6MX0%3D&branch=main)
