The announcements at the O'Reilly MySQL and Oracle Collaborate conferences last week mark an exciting milestone in the development of MySQL replication.  The purpose of this blog is to summarize those announcements and provide links to further reading, published directly by the engineers who have been working hard to take MySQL replication to the next level.

A number of significant replication enhancements were released as part of the MySQL 5.5 GA just a few months ago.

The announcements at the Oracle Collaborate and O'Reilly MySQL conferences mark an exciting milestone in the development of the MySQL Cluster database.

MySQL Cluster is already proven as a write-scalable, real-time transactional database, combining 99.999% availability with the low TCO of open source. With a distributed, multi-master architecture and no single point of failure, MySQL Cluster scales horizontally on commodity hardware to serve read and write intensive workloads.

With these enhancements announced in the Development Milestone Release, MySQL Cluster can be extended to serve a broader range of workloads.

Summary of Key Enhancements

The MySQL Cluster 7.2 Development Milestone Release and latest labs.mysql.com builds deliver enhancements based on input from the

The ever increasing performance demands of web-based services has generated significant interest in providing NoSQL access methods to MySQL - enabling users to maintain all of the advantages of their existing relational database infrastructure, while providing blazing fast performance for simple queries, using an API to complement regular SQL access to their data.

The HandlerSocket development at DeNA is a great example of community innovation, with a solution implemented as a custom plug-in and protocol for the MySQL server daemon.

We are hearing the community say they want NotOnly SQL - they want their trusted SQL RDBMS - plus, they want NoSQL techniques to access that data. So, we are previewing our NotOnlySQL solution for MySQL - delivered via memcached - with implementations to

The MySQL performance team in Oracle has recently completed a series of benchmarks comparing Read / Write and Read-Only performance of MySQL 5.5 with the InnoDB and MyISAM storage engines.

Compared to MyISAM, InnoDB delivered 35x higher throughput on the Read / Write test and 5x higher throughput on the Read-Only test, with 90% scalability across 36 CPU cores.

A full analysis of results and MySQL configuration parameters are documented in a new whitepaper (http://www.mysql.com/why-mysql/white-papers/mysql_5.5_perf_myisam_innodb.php)


In addition to the benchmark, the new whitepaper (http://www.mysql.com/why-mysql/white-papers/mysql_5.5_perf_myisam_innodb.php), also includes:
- A discussion of the use-cases for each storage engine
- Best practices for users

The convergence of telecommunications onto IP (Internet Protocol) based networks is revolutionizing today's communications industry. Communications Service Providers (CSPs) are challenged to deliver compelling new personalized services with greater agility and lower costs than ever before.

Whether they are looking to deploy new Web/Telco 2.0 applications to mobile Internet users or consolidating subscriber data within the network to support greater service personalization and targeted communications, the database plays a key role in enabling new services.

We believe MySQL is pretty much unique in the industry by providing the insight and experience to marry the innovation and speed of the Web with the proven capabilities of the carrier network. MySQL is deployed in 9 of the top 10 most trafficked sites on the web [1] including Google, Facebook
