whoami
• Chief Evangelist (in the CTO office), Percona Inc

• Focusing on the MySQL ecosystem (MySQL, Percona Server, MariaDB
Server), as well as the MongoDB ecosystem (Percona Server for
MongoDB) + 100% open source tools from Percona like Percona
Monitoring & Management, Percona xtrabackup, Percona Toolkit, etc.

• Founding team of MariaDB Server (2009-2016), previously at Monty
Program Ab, merged with SkySQL Ab, now MariaDB Corporation

• Formerly MySQL AB (exit: Sun Microsystems)

• Past lives include Fedora Project (FESCO), OpenOffice.org

• MySQL Community Contributor of the Year Award winner 2014
A Mature Ecosystem
•MySQL: 21 years old — May 1995

•Percona Server: 8 years old — November
2008

•MariaDB Server: 6 years old — February 2010

•Drizzle: 2008 - 2012 (R.I.P.)

•WebScaleSQL: March 2014
History
• 1979: UNIREG

• 1986: UNIREG on UNIX

• mSQL - freely available but not opensource

• 1995: MySQL 1.0 + MySQL AB founded

• 1996: 3.19

• 2000: GPL MySQL Server
History 2
• Shortly thereafter, the dual-license arrives —
libmysql is GPL and not LGPL like before

• May 2000: 3.23.15 - (statement based)
replication arrives 

• 2001: 3.23 GA

• 2001: InnoDB storage engine (InnoBase Oy)

• 2001: first round VC $$$, Mårten Mickos as CEO
History 3
• 2002: MySQL sued Progress NuSphere
over the Gemini storage engine

• 2003: VC Series B

• March 2003: 4.0 GA + 4.1 & 5.0 as alpha

• 2003: SAP partnership (hello MaxDB)

• 2003: Acquires Alzato (NDBCLUSTER)
History 4
• October 2004: 4.1 GA (with NDBCLUSTER)

• 2005: 5.0 tree is the focus, but it has issues

• October 2005: Oracle acquires Innobase Oy
(“InnoDB Friday”)

• October 2005: 5.0 becomes GA*

• Late 2005: Maria project starts (make a crash-
safe+transactional MyISAM)
History 5
• February 2006: VC Series C

• 2006: Netfrastructure acquired (Falcon engine)

• Pluggable storage architecture - only database
that support(ed) it

• A “fork” of MySQL Cluster in 2006

• 2006: PBXT (log-based design + performance)
… 2011
What makes engines different?
• Storage: how the data is
stored on disk

• Or in NDB (memory
+disk), CassandraSE
(access a Cassandra
Cluster), SphinxSE
(access the Sphinx
daemon) 

• Indexes: improves search
operations

• Memory usage: improves
data access for speed

• Transactions: protects the
integrity of your data
(Atomic-Consistent-
Isolated-Durable - ACID)

• Locking level: MyISAM
(table locks), InnoDB (row
locks), old BDB (page
locks)

• Data types: Data types
may be converted,
MEMORY doesn’t support
TEXT, etc.

• Caching: InnoDB caches
data & indexes, MyISAM
caches indexes only
(relying on OS disk cache
for data)

• Full-text search capability:
MyISAM has this, InnoDB
5.6 got this

• GIS: MyISAM & Aria work
(R-tree indexes exist),
InnoDB 5.7 has this too

• Backups

• Foreign Keys
History 6
• November 2007: MySQL 6.0 Alpha, 5.1 current tree
being worked on but not ready

• 2007: quiet period for IPO

• January 2008: Sun Microsystems acquires MySQL AB
for USD$1 BILLION

• June 2008: Drizzle — fork of MySQL 6.0 — modular,
fast, microkernel architecture, UTF8, etc.

• November 2008: 5.1 GA
History 7
• Late 2008: OurDelta binaries

• November 2008: Percona Server (patchset ~July)

• http://www.bytebot.net/blog/archives/2009/10/14/

Shell, X DevAPI post-GA
Open source community
• MariaDB: takes external contributors/committers

MariaDB 5.2) from Andrey Zhakov

• contributions welcome, commits not

• see: MySQL Community Contributor Award Program

Foundation member hired a new developer)

Is MySQL dying?
• “The reports of my death have been greatly
exaggerated” — Mark Twain

• MySQL ecosystem development is at its
most vibrant now than it has ever been

• Oracle has been a great steward of
pushing MySQL development forward
MySQL adoption
• MySQL Server (5.5) still leads the way in
Debian/Ubuntu (the only one you can track
via popcon)

• Followed by MariaDB Server and then
Percona Server

• Today you can also see stats on the Docker
hub, Juju Charms, etc.
OpenStack user survey
MySQL 5.7

replication

• Dynamic replication
filters

• Lossless semisync

• SHOW EXPLAIN for
connection_id

increase

• LOCK/UNLOCK
accounts

• JSON + MySQL Shell

Workbench, phpMyAdmin, SQLYog,
etc
(GNU/Linux) Distributions
• Most are defaulted to MariaDB Server 10 (some like RHEL
7 are still on MariaDB Server 5.5)

• so when you ask for mysql, you effectively get MariaDB
Server (beware!)

• Debian was hotly contesting if it should drop MySQL or
not (see: Elasticsearch)

• however, today, Debian & Ubuntu ship MySQL as
default, MariaDB Server and Percona Server as choices
Where are they now?
• Drizzle - single company opensource project
(Rackspace). Most went on to work at OpenStack

• PBXT - PrimeBase focuses on TeamDrive, out of
the engine business

• InfoBright

• Tokutek TokuDB - Percona acquires in April 2015
Future?
• MySQL 8.0 DMR is out! Look out for the interesting work behind
Cluster & group replication

• Percona Server aims to never become a fork — work closely
with Oracle. MORE FEATURES COMING in 5.7, e.g.
compressed columns (Blueprints)

• MariaDB 10.2 (beta out!) will become more of a fork with various
features like window functions, CTEs, 5.7 compatibility, etc.

• WebScaleSQL (really, fb-mysql) will skip MySQL 5.7; backports
to current tree + look at 8
MySQL 8.0 - DMR now available!
• Major refactoring - C++11, better support for ARM64/PPC

• utf8mb4

• SET PERSIST

• Bye, bye, .FRM files - transactional data dictionary

• https://jira.mariadb.org/browse/MDEV-10392 (incompatibilities)

• https://mariadb.com/kb/en/mariadb/mariadb-vs-mysql-compatibility/
