Continuent To Bring Open Source DB Replication To the Oracle World

Robert Hodges, CTO of Continuent, has an interesting blog entry about a new approach to database replication that they are undertaking. The new approach aims to provide easier access to replication for low-end Oracle users in addition to the alpha offering they already have for MySQL. "It's not a coincidence that we chose to implement MySQL and Oracle replication at the same time. MySQL has revolutionized the simplicity and accessibility of databases in general and replication in particular. For example, MySQL users have created cost-effective read scaling solutions using master/slave replication for years. MySQL replication is not free of problems, but there is no question MySQL AB helped by the community got a lot of the basics really right. On the other hand, Oracle replication products offer state-of-the-art solutions for availability, heterogeneous replication, application upgrade, and other problems, albeit for high-end users. For example, Oracle Streams and Golden Gate TDM offer very advanced solutions to the problem of data migration with minimal downtime. The big problem with these solutions is not capabilities but administrative complexity and cost."

this does not match my experience

If there is one thing that really sucks in mysql it's replication, and no, they did not get it right.

Even running top notch hardware about as redundant as you can get after running for a couple of months the master and slave can be out of sync.

I think this is one of the major remaining issues with mysql.

Keep watching. It won't be alpha for long. On the plus side we are being completely open about the development and will not deceive you about the true state of the software. Robert (the guy that wrote the original blog entry)
