Worry to delete Read replica RDS I created a read replica from RDS , and I do want to delete it. 

I am so worry about affecting the origin RDS which is in PROD . 


Is it recommended to take snapshots before deletion of read replica instance ? 
Or it is a safe action , known that AWS console shows the screen when I click on delete?
Taking a snapshot is never a bad idea when making changes in a production environment.

That said, it should be safe to delete a replica in RDS as long as you don't have any service connected to it.
