tidb

Connecting Rust and TiDB with ADBC

Instructions

Tip

If you already have a TiDB instance running, skip the steps to set up and clean up TiDB.

Prerequisites

1. Install Rust

2. Install dbc

Set up TiDB

1. Install Docker

2. Start a TiDB instance:

   docker run -d --rm --name tidb-single -p 4000:4000 pingcap/tidb

Connect to TiDB

1. Install the MySQL ADBC driver:

   dbc install mysql

2. Customize the Rust program src/main.rs as needed

   • Change the connection arguments in opts
     • Format the URI according to the DSN (Data Source Name) format used by Go-MySQL-Driver, or keep it as is
   • If you changed which database you're connecting to, also change the SQL SELECT statement in statement.set_sql_query()

3. Compile and run the Rust program:

   cargo run

Clean up

Stop the Docker container running TiDB:

docker stop tidb-single
