MySQL 8.0.0. DMR 1
7

MySQL 8.0.0 DMR 1
• The next version of MySQL will be 8.0
– MySQL 6 is a canceled version (2007)
– MySQL Cluster 7 exists
– 5.7 → 8.0 is a “nice” jump (“Just drop the 5.”)
• First Development Milestone Release available
– A DMR is produced from TRUNK every 3-6 months
– Includes everything that is new in TRUNK since the previous DMR.
– The goal is to produce DMRs with RC (release candidate) quality.

The character set for the Web
MySQL 8.0: UTF-8
• New! Support for the latest Unicode 9.0
• Per-country collation rules
– Accent Sensitive
– Case Sensitive
• Based on UCA DUCET
• UTF8MB4 as the default character set
– Project started in MySQL 5.7
– Many improvements to reduce performance impact
• UTF-8 is the dominating character set
in today’s applications
• CJK users are adopting UTF-8
– Driven by “adopted words” from
foreign languages
• EN users are adopting UTF-8
– Driven by support for emojis
https://en.wikipedia.org/wiki/UTF-8

MySQL 8.0
Continuing the JSON Experience
• MySQL Document Store
• Administer MySQL via the MySQL Shell
• New JSON functions
– JSON_ARRAYAGG()
– JSON_OBJECTAGG()
SELECT blog.*,
  JSON_ARRAYAGG( JSON_OBJECT("author", blog_comment.author, "body", blog_comment.body) ) AS comments
FROM blog
JOIN blog_comment
  ON blog.id = blog_comment.blog_id
GROUP BY blog_id;
+++++
| 1 | Hello World | This is my new Blog! | [{"body": "Great blog!", "author": "A Friend"}, {"body": "Great new blog", "author": "Best Friend"}] |
+++++
| 2 | spam trap   | spam goes here       | [{"body": "Buy these pills to enlarge your blog", "author": "Visitor"}]
+++++

MySQL 8.0: Invisible Indexes
• Indexes are “hidden” to the MySQL Optimizer
– Not the same as “disabled indexes”
– Contents are fully up to date and maintained by DML
• Two use cases:
– Soft Delete (Recycle Bin)
– Staged Rollout
Feature Request
from DBAs
• I don’t think this index is used any more:
ALTER TABLE Country ALTER INDEX c INVISIBLE;
• I need to revert:
ALTER TABLE Country ALTER INDEX c VISIBLE;
• It is now safe to drop:
ALTER TABLE Country DROP INDEX c;
Example Usage:

MySQL 8.0: Persist Configuration
• Persist GLOBAL Dynamic Server Variables
– SET PERSIST
sql_mode='STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION';
• Examples Include:
– SQL Mode
– Offline Mode
– Read Only
• Requires no filesystem access
Cloud Friendly

MySQL 8.0: Transactional Data Dictionary
• Increased Reliability
• Using InnoDB internally for data dictionary
– No FRM files
– No DB.OPT files
– No TRG files
– No TRN files
– No PAR files
