Enable logical replication

Create or modify a parameter group with rds.logical_replication = 1 and apply it to your RDS instance.
This requires a reboot of your RDS instance. Plan accordingly.
2

Grant replication permissions

Connect to your RDS instance and grant the replication role to your user:
GRANT rds_replication TO your_user;
3

Get your connection string

Your RDS connection string looks like:
postgresql://user:[email protected]:5432/mydb
You can find the hostname in the RDS Console > Databases > your instance > Connectivity & security.
4

Connect your database

ardent connector create postgresql postgresql://user:[email protected]:5432/mydb
Ardent will verify your setup and begin replicating your database. This may take a few minutes depending on data size.
5

Create your first branch

ardent branch create my-feature
Done. You now have an isolated copy of your RDS database — schema, data, and all. The CLI returns a connection URL you can use anywhere.
