Three common MySQL database design mistakes

This post details three common MySQL database design mistakes: suboptimal data type selection (e.g., INT for IDs running out of space, or over-provisioning for zip codes), the impact of missing or redundant indexes on query performance and storage costs, and the improper storage of semi-structured data by using TEXT columns instead of the native JSON type. It offers solutions like using appropriate integer sizes, managing indexes effectively, and leveraging MySQL's JSON capabilities for efficient querying and indexing.
