2003 MySQL acquires Alzato

 “It must be possible to install the software in 15 minutes.”
 “The source must be available to everyone.”
 “Everyone can download the software.”
 Chat systems, Agile development, 250 emails/day

RESULT:
MySQL Cluster became much easier to use.
And Open Source.


2008 Sun acquires MySQL

 “Yeah, sure it is fast, but not on real computers.”
 “MySQL is only one of many products at Sun.”
 “There are people to help, especially with performance.”

RESULT:
MySQL performance started to increase a lot.


2010 Oracle acquires Sun

 “Oracle drives innovation. Make MySQL a better MySQL.”
 “Security is key.”
 “Quality and testing is essential.”
 MySQL & InnoDB in the same company

RESULT:
More development than ever before. More secure, more
features, more testing. Huge InnoDB & MySQL performance
improvements.

- InnoDB for better transactional throughput, availability
- Optimizer for better query execution times, diagnostics
- Replication for high availability, data integrity
- Performance Schema for better instrumentation
- Other Important Enhancements

 Available Now! Get it here:
dev.mysql.com/downloads/mysql/

MySQL 5.6: InnoDB
 Key-value access to InnoDB
Best of Both Worlds
- via industry standard Memcached API
- Use existing Memcached clients
Application - Bypasses full SQL parsing
SQL NoSQL  NotOnlySQL access
(Memcached
(MySQL Client) - For key-value operations
Protocol)

mysqld
- SQL for rich queries, JOINs, FKs, etc.
MySQL Server Memcached plugin  Implemented via:
- Memcached plug-in to mysqld
InnoDB Storage Engine - Memcached mapped to native InnoDB
API

#1 DBA Concern - Is My Data Safe?
…Who can see it? Do I know…

…What did they see? …what happened?

…Who can change it? …and when?

…What did they change? Can I prove what I believe
to be true?

…Are my apps compliant with company and legal requirements?
