Connecting Python and CrateDB with ADBC

Instructions

Tip

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

Start a CrateDB instance:

docker run -d --rm --name cratedb -p 4200:4200 -p 5432:5432 crate -Cdiscovery.type=single-node

Install the PostgreSQL ADBC driver:
```
dbc install postgresql
```
Customize the Python script main.py as needed
- Change the connection arguments in db_kwargs
  - Format uri according to the connection URI format used by PostgreSQL, or keep it as is
- If you changed which database you're connecting to, also change the SQL SELECT statement in cursor.execute()
Run the Python script:
```
uv run main.py
```

Stop the Docker container running CrateDB:

docker stop cratedb
