With MySQL being widely deployed for web-tier applications, a consistent message from our mutual customers has been the need for better master-slave replication than current solutions. Scalability and reliability with seamless failover and no performance loss are absolutely crucial for them. Tungsten delivers this.

San Jose, CA (PRWEB) September 3, 2008

Continuent, Inc., a leading provider of commercial open source solutions for database replication and scale-out, today announced an advanced replication for MySQL® with its Tungsten Replicator. Continuent Tungsten™ is an open source stack, a collection of integrated projects, for database scale-out using commodity hardware.

MySQL's built-in database replication has been a key component of horizontal scaling solutions for many years. However, it also has a number of limitations that are well-known in the MySQL community. At the 2008 MySQL Conference & Expo, Monty Widenius, founder and original developer of MySQL, highlighted key replication weaknesses (http://www.scribd.com/doc/2575733/The-future-of-MySQL-The-Project) such as:

Replication is not fail safe
No synchronous options
No checking consistency option
Setup and resync of slave is complicated
Single-thread on the slave
No multi-master
Only InnodDB synchronizes with the replication (binary) log.

As a longstanding MySQL partner and an expert in high-end replication solutions, Continuent has taken steps to answer Monty's challenge and go beyond it as well. The initial feature set for Continuent Tungsten Replicator includes:

Simple set-up procedure
Proper handling of master failover in presence of multiple slaves (for high availability)
Master/slave replication of one, some, or all databases
MySQL statement replication
Checksums on replication events
Table consistency check mechanism
Runs on Linux, Solaris and Windows.

Continuent Tungsten roadmap includes:

Graphical Management Tools
Oracle® support
PostgreSQL support
MySQL row replication
Heterogeneous replication (for example MySQL to Oracle and vice versa)
Multi-master via bi-directional replication with conflict resolution
Semi-synchronous replication
Parallel update on slaves to increase performance
Proxying support to reduce or eliminate application changes.

The Continuent Tungsten architecture is database-neutral, which means that the same framework supports a number of different databases. This is convenient for users, who can use a single product to replicate data on different database types. It is also a cornerstone of heterogeneous replication, which supports data integration projects between MySQL and other databases such as Oracle.

"As a MySQL Gold Partner, we have been offering synchronous master-master replication solution for years," said Eero Teerikorpi, CEO at Continuent. "With MySQL being widely deployed for web-tier applications, a consistent message from our mutual customers has been the need for better master-slave replication than current solutions. Scalability and reliability with seamless failover and no performance loss are absolutely crucial for them. Tungsten delivers this."
