In a past post here I did an overview of different index types. I said in that post that I think filtered indexes could be more popular. In this post I will cover fixing some of the problems caused when you first introduce rowstore filtered indexes to a SQL Server database.
Some of you have probably been there already. You’ve put in your first filtered index on a database only to find an issue has happened. I’ve witnessed these issues at a few places. This will hopefully reduce the pain.
I’ve definitely experienced the third issue (which also pops up when using parameterized queries, so the optimizer doesn’t know that it can use the filtered index), but never the first two.
