Linking Redshift as a source

The Redshift connector can link your database tables to PostHog.

To link Redshift:

1. Go to the Data pipeline page and the sources tab in PostHog
2. Click New source and select Redshift
3. Enter your database connection details:
   • Host: The hostname or IP of your Redshift cluster like my-cluster.abc123.us-east-1.redshift.amazonaws.com.
   • Port: The port your Redshift cluster is listening on. The default is 5439.
   • Database: The name of the database you want like analytics_db.
   • User: The username with the necessary permissions to access the database.
   • Password: The password for the user.
   • Schema: (Optional) The schema for your database. Leave blank to browse and sync tables from all schemas, or specify one to limit the selection. The default is public.
4. Click Next

The data warehouse then starts syncing your Redshift data. You can see details and progress in the sources tab.

Permissions: The Redshift source only requires read permissions on the schemas and tables you intend to sync.

Configuration

Selecting columns

By default, PostHog syncs all columns from each table. To sync only specific columns:

1. During source setup, click Columns next to any table in the table picker.
2. Uncheck columns you don't want to sync.
3. Primary key columns and the incremental sync field (if configured) are always synced and cannot be disabled.

You can also change column selection after setup:

1. Go to the sources tab and click your Redshift source.
2. Click Configure next to any schema.
3. Under Columns, select which columns to sync.

Inbound IP addresses

We use a set of IP addresses to access your instance. To ensure this connector works, add these IPs to your inbound security rules:
