A covering index is a fantastic query performance optimization. An index covers a query when the index has all the data needed to execute the query, so the server can retrieve the query’s data without reading any rows or documents. Covered queries are usually SELECT queries, but in addition to reads, indexes can cover portions of what a write query needs to do its work.

In this article I’ll explain what a covering index is in a bit more detail; the technical implementation and caveats in MySQL, PostgreSQL, and MongoDB; and how to check that a query is using a covering index.

What’s a Covering Index?

A covering index, or index-covered query, doesn’t refer just to an index. Instead, it’s the combination of a query and an index: the index covers the query. An index that covers one query might not cover another query, so “covering” doesn’t solely describe the index, …
