One of the most popular new features of MySQL 5.7 was JSON support. Now you can use SQL to search, extract information from, and change JSON documents. MySQL 8.0 takes this a step further. Using the JSON_TABLE function, you will be able to construct relational tables based on the contents of JSON documents. This way, you will be able to use the power of SQL to process JSON. For example, you can use SQL aggregate functions on your JSON data, or use the WHERE clause to find interesting objects within a JSON array.
This lightning talk will give a short introduction into how JSON_TABLE provides the missing link when processing JSON documents in MySQL.
