SQL Server: The danger of large data types

Databases are platforms that are designed to securely store and retrieve your data. Perhaps that’s why they’re called a data “base”? So if your data is in a base, you’d want to lay it out in some logic way.

Distributed Writes

In SQL Server, scaling out reads (i.e. using Active secondary replicas via AlwaysOn Availability Groups) is a lot easier than scaling out writes.  So what are your options when you have a tremendous amount of writes that scaling up will not handle, no matter how big your server is?… Read more

Does rebuilding my clustered index also rebuild my non-clustered indexes?

I’ve been working with SQL Server for many years now, and up until recently, I assumed that rebuilding any clustered index would cause non-clustered indexes to be rebuilt as well, because the non-clustered index includes the clustered index in it.
