JSON in MySQL 5.7

Please join Percona's Consultant David Ducos as he presents "JSON in MySQL 5.7".
Since being internally implemented in MySQL 5.7, we have the option of using JSON as a data type. In this webinar, we will review some of the useful functions that have been added to work with JSON.
We will examine and analyze how JSON works internally, and take into account some of the costs related to employing this new technology.
At the end of the webinar, you will know the answers to the following questions: 
  • What is JSON?
  • Why don’t we keep using VARCHAR?
  • How does it work? 
  • What are the costs?
  • What limitations should we take into account?
  • What are the benefits of using MySQL JSON support?
