Presenting the newly released MySQL Cookbook 4th edition to help developers and administrators to understand simple to complex recipes. MySQL Cookbook 4th edition was released this summer. We are the book's authors and will show you how to "cook" MySQL. We will show you a few tasks with different priorities, such as JSON in MySQL for those who need flexibility, modern SQL for analytics, and Group Replication for high availability. We will also show how to write programs using JavaScript and Python languages, X DevAPI, and MySQL Shell. We will touch on some of the exciting features of MySQL Spatial Indexes and Geographical Data, Using a Full-Text Search, and more. We're hoping this talk will interest developers and administrators of MySQL. I'd like to share my authoring experience e and knowledge about an open-source database product MySQL. I also want to touch on this journey's technical and non-technical aspects giving vision and inspiration to future authors. At the end of the talk, I will give away one printed copy of the MySQL Cookbook 4e to an audience after a trivia question.

8. How did I end up there?
● It wasn’t by luck maybe co-incidental
● Wanted to author one before
● Failed attempts
● Recognition
● Pandemic

9. Stages ?
● Preparations
○ Agreement on the book (pages, percentile of content if new release)
○ Contracts signed
○ Authoring platform discussions
■ Docbook over XML / Asciidoc
■ This is important piece of decision
○ Editor(s) assigned by O’reilly
○ Supervisor assigned by O’reilly

10. Stages ?
● Authoring
○ Start with difficult chapters
○ Allow research time
○ Use of editor (Grammarly) and available resources
○ Getting inside (co-author) and outside help
○ Review process
○ Final edits before many final reviews and approvals
@ChistaDATA Inc. 2022
@ask_dba

11. Stages ?
● Putting all together
1. Authoring is confirmed by the author (if co-authoring) if not this will be done by
technical reviewers
2. Reviewed by immediate editor
3. Chapters passes quality assurance by marking them complete and ready for pre-release.
4. While pre-releases published by chapters other chapters ongoing and technical reviews
starts.
5. They all randomly come back with feedback

12. Builds ?
● Every version is a complete book repo in GitLab.
1. Use gitlab to pull changes. If two authors working together make sure to be up
to date.
2. Edit changes in a chapter
3. Push changes to repo
4. Push all updates, instructions to code repo (GitHub)
5. Make a compile request as pdf
6. Review (again)

13. Production Schedule ?
1. Cover of the book (illustrations)
2. Pre-copyedit cleanup (Code blocks, Wording, Grammar and Spelling)
3. Copyedit review
4. Quality Control #1
5. Praise quotes for back cover
6. Index review
7. Quality Control #2

16. A new book? Maybe
● I’m going to be co-authoring :
○ Database Design and Modeling for MySQL and PostgreSQL
Details coming soon…

17. What’s in it?
Problem & Solution Recipes
Problem
You want to store and query geographic coordinates effectively.
Solution
Use MySQL’s improved Spatial Reference System.

18. MySQL’s improved Spatial Reference System
Creating geometries in various formats
Converting geometries between formats
Accessing qualitative and quantitative properties of geometry
Describing relations between two geometries
Creating new geometries from existing ones

19. Different variations of geographic data references
mysql> SELECT * FROM INFORMATION_SCHEMA.ST_SPATIAL_REFERENCE_SYSTEMS
-> WHERE SRS_ID=4326 OR SRS_ID=3857 ORDER BY SRS_ID DESC G
*************************** 1. row ***************************
