RAM usage

[ymguerra]

Hello, I was investigating a bit about tree structures and I found this library. In a personal project I am working on I have something similar to what this library help to solve. So I was testing this library and was working working great until I decide to added it to an existent model, this model has ~ 400mil records and then in the post_migrate signal when calling sender_model.update_tree() it use more than 20GB RAM.

Is there a work around for this?
