PBXT and a scalable BLOB streaming infrastructure

As Kaj Arnö already mentioned in his blog, we have a vision for MySQL and it is called a scalable BLOB streaming infrastructure. Our plan is to build this into and around the MySQL architecture with the help of MySQL and the community.

It is a "big picture" idea and in this way a response to Robin Schumacher's question: The MySQL Vision - What do you see?. But at the same time it is very relevant and practical in the context of the Web 2.0 world.

The design of the system includes a client-side library which extends the existing MySQL client API, a stream based communications protocol and a scalable back-end which is (at least partially) linked into the MySQL server. In short, we want to make it possible to put BLOBs of any size in the database.

The system will be open, and available to all engines running under MySQL. Of course, I believe PBXT has the ideal design and performance characteristics to support this new infrastructure.

Many say that their programs run fine with the BLOBs stored in the filing system. And this is true, but what about transactional consistency, backup and replication? And what about scale-out for the storage and delivery of this data? Simply put, we know these are significant issues from our customers in the print and web publishing business that need this functionality.

And, when you think about it, media streaming has a very promising future. I believe it's becoming more important for an increasing number of developers. So this is more about opening up new opportunities and extending the reach of MySQL into new areas.

We have a pretty good idea of the basic design of the system, but this is just the starting point. The design must reflect the requirements of the users and developers, so our first step is to get as many as possible in the MySQL community together who have an interest in this technology.

We want to know what features and characteristics of such a system are important to you. What are your requirements of such a system?

To this end I am arranging a BoF on scalable BLOB streaming at the MySQL user conference next month. This will be a great opportunity to get together and discuss the subject with all who are interested, so I hope you will join me.
