Taming the Database: How Observability Spurs Continuous Delivery

For tech professionals it’s intuitive that higher software delivery and operational performance — SDO performance is a new-ish moniker — yields higher organizational performance, or at least substantially contributes to it.  But now, five years of research from the DevOps Research and Assessment (DORA) team have consistently provided this as a data-driven conclusion for business leaders too. And when it comes to the specific technical practices that improve SDO performance, rising decisively to the top is a core DevOps workflow: continuous delivery—discovering what positively impacts it, honing those catalysts, and optimizing.

Inspecting Index Usage In MySQL, PostgreSQL, and MongoDB

In my recent post about the Left-Prefix Index Rule, I explained how queries can use all or part of a compound (multi-column) index. Knowing what makes an index fully usable by a query is important, but it's also important to know how to figure out how much of an index a query is able to use. In this article I'll show you how to do this by reading the query's explain plan. This article covers MySQL, Postgres, and MongoDB.

The Left-Prefix Index Rule

There's an important heuristic in database indexing that I call the left-prefix rule. It helps you understand whether the database will be able to make the best use of a multi-column index to speed up a query. It's one of a small handful of really important things to understand about indexes!


The left-prefix rule can be confusing, but once you grok it, it's simple and easy to use. It applies to MySQL, PostgreSQL, MongoDB, and many other databases. In this post I'll explain what the left-prefix rule means and how it works.
