About my blog

I am using this blog to write about how query processing works in SQL Server.

Some of the topics that I write about:

  • How to read and understand query plans and query operators.
  • How different query plans affect performance.
  • The tradeoffs made by the query optimizer when choosing query plans.
  • How subtle changes to a query can affect the choice of plan and impact performance.
