Should I use primary database connection string or read only connection string

Let’s say i want to scale my database for different data centers. What I need to do is to replicate the primary database and create a read-only replicate of it. And DO gives two connection strings, one is the primary and the other is read-only. Which connection string should i use for my app?

Hi @matthewbennett,

If you want read and write to happen to your managed database cluster you will have to use a primary database connection string.

And when a read-only node is at the different data center which is going to be used for read operations; you can use a read-only node connection string. which can offload read requests/analytics traffic from the primary database.

For more information on read-only nodes:

I hope this helps!
