Highlights

Article: Introduction to MySQL 5.5 (Performance and Scalability Improvements)

It's been a busy year for MySQL. Perhaps you've heard. Here are some recent improvements to the speed, scalability, and user-friendliness of the MySQL database and the InnoDB storage engine that we think deserve their own headlines. Now is a great time to beta test the 5.5 release and give feedback to the MySQL engineering team.

White Paper: MySQL Cluster Connector for Java

As part of the MySQL Cluster 7.1 release, the MySQL Cluster Connector for Java implements a high performance and easy-to-use native Java interface and OpenJPA plug-in that directly maps Java objects to relational tables stored in the MySQL Cluster database.

By eliminating data transformations into SQL, users get lower data access latency and higher throughput. As a result, the development of Java applications is simplified with faster development cycles resulting in accelerated time to market for new services.

White Paper: MySQL Cluster Manager

MySQL Cluster Manager simplifies the creation and management of MySQL Cluster Carrier Grade Edition by automating common management tasks. As a result, Database Administrators (DBAs) and Systems Administrator are more productive, enabling them to focus on strategic IT initiatives that support the business and respond more quickly to changing user requirements.

PlanetMySQL Blog: InnoDB recovery is now faster... much faster!
Inaam Rana

One of the well known and much written complaint regarding InnoDB recovery is that it does not scale well on high-end systems. Well, not any more. In InnoDB plugin 1.0.7 (which is GA) and plugin 1.1 (which is part of MySQL 5.5.4) this issue has been addressed. Two major improvements, apart from some other minor tweaks, have been made to the recovery code. In this post I'll explain these issues and our solution for these.

PlanetMySQL Blog: MySQL 5.5.4-m3 scales to 32 cores
Mikael Ronstrom

The newly released MySQL 5.5 beta version MySQL 5.5.4-m3 has a large number of significant performance improvements. These improvements make it possible for MySQL to scale well even on 32-core servers. The graph below shows how MySQL 5.5.4-m3 scales from 12 cores to 32 cores using a single thread per core.

PlanetMySQL Blog: InnoDB Performance Schema
Jimmy Yang

With the plugin 1.1 release, InnoDB will have full support of Performance Schema, a new feature of MySQL 5.5 release. This allows a user to peak into some critical server synchronization events and obtain their usage statistics. On the other hand, in order to make a lot of sense of the instrumented result, you might need some understanding of InnoDB internals, especially in the area of synchronization with mutexes and rwlocks.

PlanetMySQL Blog: Better Scalability with Multiple Rollback Segments
Sunny Bains

The original motivation behind this patch was the infamous Bug#26590 - MySQL does not allow more than 1023 open transactions. Actually the 1024 limit has to do with the number of concurrent update transactions that can run within InnoDB. Where does this magic number come from?

PlanetMySQL Blog: MySQL: Partition-wise backups with mysqldump
Roland Bouman

To whom it may concern, in response to a query from André Simões, I slapped together a MySQL script that outputs mysqldump commands for backing up individual partitions of the tables in the current schema. The script is maintained as a snippet at MySQL Forge.

PlanetMySQL Blog: Hyper Threading Performance
Venu Anuganti

It's been a while anyone talked about Intel's Hyper-Threading performance when it comes to databases. There were enough posts about disabling Hyper-Threading completely when it comes to MySQL/InnoDB workloads way back when we had enough issues with scalability of InnoDB on multi-core systems. But things have changed quite a bit in the past year or two in terms of multi-core support.

PlanetMySQL Blog: Index only
Mark Callaghan

A problem with SQL is SQL. It is easy to write queries that require random IO in the worst case. It is usually easy to find queries that do too much random IO on a NoSQL system as you must code the extra data fetches manually.

PlanetMySQL Blog: Using ClusterJ (part of MySQL Cluster Connector for Java) - a tutorial
Andrew Morgan

ClusterJ is part of the MySQL Cluster Connector for Java which is currently in beta as part of MySQL Cluster 7.1. It is designed to provide a high performance method for Java applications to store and access data in a MySQL Cluster database. It is also designed to be easy for Java developers to use and is "in the style of" Hibernate/Java Data Objects (JDO) and JPA.
