In one of the recent interview, I met quite a few interesting candidates. It is common for employees ask many questions during an interview, but there are times when candidates also ask questions back to the interviewee. I was asked following question recently.

SQL SERVER – How to Rename a Column Name or Table Name

[Notes from Pinal]: If we get one server, we want two servers, and if we get two servers, we want four servers. If we know we are going to get only two servers, we try our best to get maximum out of our available server. Maximum utilization of resources is always our primary goal. In this blog post we are going to talk about almost the same story where we try to get maximum out of our servers. Let us assume that we have two servers, how do we get maximum performance from them. Well, our generic answer would be that we will keep the most important task on our primary server and move all the not so important task on secondary server. This is common sense and essential too. This is when I reached out to Eduardo and asked him what can we do to make our primary server faster by offloading backups to secondary replica.
