The MySQL JSON data type

This post introduces and explains the MySQL JSON data type, covering its structure, use cases (log output, API responses, configuration data, denormalization), and caveats (storage overhead, indexing limitations). It demonstrates common operations using MySQL JSON functions such as JSON_ARRAY, JSON_TYPE, JSON_EXTRACT, and JSON_ARRAY_APPEND, and provides examples of table creation and data insertion. It also references related articles on MySQL integer and VARCHAR data types.
