At that point you're dealing with a graph instead of a hierarchy. If you're using MySQL you may want to look at the following storage engine by an associate of mine: http://openquery.com/products/graph-engine

Could this be made to work for hierarchies where a child can have more than one parent?

Very nice and concise article, Mike. I bought Joe Celko’s book that you referenced and have skimmed, then read it. Your article helps me to understand the Nested Set model. I’m an old dog who has been writing adjacency list hierarchies since the early nineties. I always thought there could be ‘better way’, and this is certainly it. Thanks for taking the time to explain it all, Mike.

Hey, I get release announcements about SQLyog and MONyog all the time. Would you getting so successful that you had to send millions of such announcements at a time move you into the realm of being a spammer?

Glad you liked it Geoff. There’s certainly nothing wrong with using Postfix, I’ve seen clients scale it horizontally to move millions of messages per hour and I personally find smtp-source and smtp-sink to be indispensable tools (and as a former MySQL employee I’m an Open Source fan).

The main thing to me is that when I walk into those clients with dozens of Postfix servers and cut their server footprint down to 1/10th (77 to 7 in one case, 120 to 12 in another), it shows that there’s a point where it literally becomes cheaper to use a paid solution, not to mention easier.

Great post – passionately argued as you’d hope a good presales engineering manager would for benefits, but with enlightened great examples that even Postfix stalwarts doing millions of messages a month can take away value.
