I realized that it is important to understand the insights of the performance schema and how we can make effective use of it.

Without build optimizations (incremental builds, caching, we will get to those soon) this will eventually become unmanageable as well — think about going through all images in a website: resizing, deleting, and/or creating new files over and over again. Under the hood, it simplifies a lot of the work to the server-side.

This was convenient for the demos but repeatable read isolation isn’t common in everyday use. When SQL Server reads data under locking read committed isolation (the default for non-cloud offerings) and chooses row-level locking granularity, it normally only locks one row at a time. SQL Server solves this problem using lock classes.

One of the more perplexing problems to troubleshoot in SQL Server can be those related to memory grants. Some queries need more memory than others to execute, based on what operations need to be performed (e.g. sort, hash). The Sales.Orders table has about 4.6 million rows, and the Sales.OrderLines table has about 9.2 million rows.

While an eager index spool may only appear on the inner side of an nested loops apply , it is not a "performance spool". SQL Server does not support parallel inserts to a b-tree index. Anyway, the point is that sometimes it is not possible for SQL Server to pass an apply outer reference as a parameter to an sTVF.

Font loading has long been a bugbear of web performance, and there really are no good choices here. The thinking here was that it was better for performance to display the text as quickly as you can , even if it’s in the fallback font, and then to swap the font in when it finally downloads.
