Snake draft sorting in SQL Server, part 4

In the previous posts in this series (part 1, part 2, part 3), I described how I have optimized a long-running set of routines by processing databases, tables, and even subsets of tables in parallel. This leads to many separate jobs that all kick off at roughly the same time

Is date zero valid and if so what day is it?

In part 2 of this series, I showed an example implementation of distributing a long-running workload in parallel, in order to finish faster. In reality, though, this involves more than just restoring databases. And I have significant skew to deal with: one database that is many times larger than all the rest and has a higher growth rate.

Snake draft sorting in SQL Server, part 2

Snake draft sorting in SQL Server, part 1

I recently had a restore job where I needed to split the work up into multiple parallel processes (which I’ll refer to here as “threads”). I wanted to balance the work so that the duration was something significantly less than the sum of the restore times

SQL Logic

In this article, I will discuss the history and thinking behind several types of logic that are typically associated with writing relational database code.
