(MySQL releases 3.23 GA) 2003 MySQL acquires Alzato

(MySQL 4.0 GA) 2004 MySQL 4.1 GA 2005 MySQL 5.0 GA

2008 Sun acquires MySQL MySQL 5.1 GA

2010 Oracle acquires Sun MySQL & InnoDB in same company MySQL 5.5 GA

2012 MySQL 5.6 RC, MySQL Cluster 7.3 DMR, MySQL Enterprise Backup 3.8, Connector Python GA, ...

MySQL Replication, Connectors,

Enterprise Backup, Utilities


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.

MySQL 5.6 RC


MySQL 5.6 builds on MySQL 5.5 by improving:

- 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

MySQL 5.6 Release Candidate


Better Performance, Scalability- Removal of legacy mutexes, CPU cache sharing- Improved threading and concurrency- Optimizations for Read Only workloads- SSD optimizations

Better Availability- Online DDL operations- Dump, restore/warm buffer pool

More Flexibility- Full Text Search - Transportable Tablespaces- NoSQL, Key-value access to InnoDB

MySQL 5.6: InnoDB


Key-value access to InnoDB- via industry standard Memcached API- Use existing Memcached clients- Bypasses full SQL parsing

NotOnlySQL access- For key-value operations- SQL for rich queries, JOINs, FKs, etc.

Implemented via:- Memcached plug-in to mysqld - Memcached mapped to native InnoDB

API- Shared process for ultra-low latency
