There are some exceptional tools that can be used for WordPress development that make the process way easier than it would be otherwise. I didn’t know about some of these early on in my WordPress development days, so for those of you who might not be familiar with them, I’d like to share.
WordPress uses wp_posts to store post, page, and Custom Post Type (CPT) data the wp_postmeta table for Custom Metabox data. To retrieve this data you have to read for the post plus multiple linked postmeta rows. In this post, we conquer postmeta with subqueries.
Redis is “an open source (BSD licensed), in-memory data structure store, used as a database, cache and message broker. It supports data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes with radius queries and streams.” Translation? It makes websites run faster.
