citus

Connecting Go and Citus with ADBC

Instructions

Tip

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

Prerequisites

1. Install Go

2. Install dbc

Set up Citus

1. Install Docker

2. Start a Citus instance:

   docker run -d --rm --name citus_standalone -p 5432:5432 -e POSTGRES_PASSWORD=password citusdata/citus

Connect to Citus

1. Install the PostgreSQL ADBC driver:

   dbc install postgresql

2. Customize the Go program main.go as needed

   • Change the connection arguments in the NewDatabase() call
     • 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 stmt.SetSqlQuery()

3. Run the Go program:

   go mod tidy
   go run main.go

Clean up

Stop the Docker container running Citus:

docker stop citus_standalone
