Implementing Closure Tables for Hierarchical Data in Redis

Interesting question raised by Hugo on the Redis group about modeling closure tables in Redis. Didier Spezia offers a solution based on sorted sets.

The OP linked to Rendering Trees with Closure Tables and Models for hierarchical data to explain closure tables. The slidedeck at the second link is worth a post by itself.
