"Building on Quicksand" Paper for CIDR (Conference on ... Towards Robust Distributed Systems. Trading Consistency for Scalability in Distributed Architectures. One of the key aspects of the system architect's role is to weigh up conflicting requirements and decide on a solution, often by trading off one aspect against another.

Trading Consistency for Scalability in Distributed Architectures

As systems become larger and more complex so more and more of the conventional wisdom about how applications should be built is being challenged. At last year's QCon conference in London in March, for example, Dan Pritchard gave a talk about eBay's architecture. Two data streams for a happy website. One of the most important architectural decisions that must be done early on in a scalable web site project is splitting the data flow into two streams: one that is user specific and one that is generic.

If this is done properly, the system will be able to grow easily. On the other hand, if the data streams are not separated from the start, then the growth options will be severely limited. Asynchronous Architectures. All computers wait at the same speed -- Dr.

Scalability Best Practices. Eventually Consistent. I wrote a first version of this posting on consistency models in December 2007, but I was never happy with it as it was written in haste and the topic is important enough to receive a more thorough treatment.

Eventually Consistent

ACM Queue asked me to revise it for use in their magazine and I took the opportunity to improve the article. I posted an update to this article in December 2008 under the tile Eventually Consistent - Revisted. - please read that article instead of this one. I am leaving this one here for transparency/historical reasons and because the comments helped me improve the article.
