I am co-author and tech editor of Microsoft SQL Server 2012 Internals and Microsoft SQL Server 2008 Internals both by Kalen Delaney et al and published on 2013 and 2009 respectively. I co-wrote chapters 4 “Special Databases”, and 10 “Query Execution” of the SQL Server 2012 Internals book, which were originally written by Kalen Delaney and Craig Freedman, respectively.
SQL Sentry published High Performance Techniques for SQL Server, Volume 2 on Amazon, including articles from SQLPerformance.com. It includes my articles “A First Look at the New SQL Server Cardinality Estimator” and “SQL Server 2014 Incremental Statistics”.
