MySQL 5.7 was the next received version of the most popular database on the web. But now MySQL is available with many new features plus improved performance. First there is a true data dictionary to store meta data instead of a series of files that tie up inodes; the good news is that you can now have millions of tables in a schema and the bad news is that you can not have millions of tables in a schema. Common Table Expressions and Windowing Functions to make it easier to write sub-queries and to perform analytics on your data. The new scheduler handles higher data contention levels, you get rue descending indexes, UTF8MB4 support (and it is the default character set), roles, and better JSON support.
