Connecting Python 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 uv

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 Python script main.py as needed

   • Change the connection arguments in db_kwargs
     • Format 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 cursor.execute()

3. Run the Python script:

   uv run main.py

Clean up

Stop the Docker container running TiDB:

docker stop tidb-single
