About MySQL Cookbook 4th Edition
● O’reilly Book previously authored by Paul Dubois 3 editions
● Solutions for Database Developers and Administrators
● More than 950 pages of recipes for specific database challenges
● It took two years of authoring, rewriting, reviewing, editing and
learning.
● Co-authored with Sveta Smirnova - MySQL Expert / Author , Percona
@ask_dba

How did I end up there?
10,000 hours?
@ask_dba

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

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
@ask_dba

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
@ask_dba

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
@ask_dba

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)
@ask_dba

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
@ask_dba

Became an O'reilly Author
● Authored blogs
● Attempted to author booklet
○ Invited many co-authors
○ Talked to other editors
● Given talks online and offline
○ Mentored others to give talks
● On the field and always focused on same subject (Open Source, MySQL, Databases)
● Got an invitation by long time friend and colleague Sveta Smirnova
@ask_dba

Key Takeaways
● Talk to other authors
● Platform research
● Keep close track of agreements and details
● Organize your time in advance (allow extra time)
● Do not overcommit (work / life / book) balance
● More on this in another blog - MySQL Cookbook 4th Edition
● Details about the book in Percona University Nov 5 10:00 - 18:00
@ask_dba

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

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.

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

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 ***************************
SRS_NAME: WGS 84

SRS_ID 4326 represents map projections used in Google
Maps
mysql> CREATE TABLE poi
-> ( poi_id INT UNSIGNED AUTO_INCREMENT NOT NULL PRIMARY KEY,
-> position POINT NOT NULL SRID 4326, name VARCHAR(200));
Query OK, 0 rows affected (0.02 sec)

Insert GeoSpatial data with ST_GeomFromText()
mysql> INSERT INTO poi VALUES (1, ST_GeomFromText('POINT(41.0211 29.0041)', 4326),
-> 'Maiden's Tower');
Query OK, 1 row affected (0.00 sec)
msyql> INSERT INTO poi VALUES (2, ST_GeomFromText('POINT(41.0256 28.9742)', 4326),
-> 'Galata Tower');

Create SPATIAL index
mysql> CREATE SPATIAL INDEX position ON poi (position);
Query OK, 0 rows affected (0.01 sec)
Records: 0 Duplicates: 0 Warnings: 0

Measure the distance between coordinates ST_Distance()
mysql> SELECT ST_AsText(position) FROM poi WHERE poi_id = 1 INTO @tower1;
mysql> SELECT ST_AsText(position) FROM poi WHERE poi_id = 2 INTO @tower2;
mysql> SELECT ST_Distance(ST_GeomFromText(@tower1, 4326),
-> ST_GeomFromText(@tower2, 4326)) AS distance;
+--------------------+
| distance |

1 row in set (0.00 sec)

Improved Earth’s spherical shape with
ST_Distance_Sphere ()
mysql> SELECT ST_Distance_Sphere(ST_GeomFromText(@tower1, 4326),

+--------------------+
| dist |

1 row in set (0.00 sec)

Set a polygon with coordinates
mysql> SET @poly := ST_GeomFromText ( 'POLYGON(( 41.104897239651905 28.876082545638166,
-> 41.05727989444261 29.183699733138166,
