hari

Hari is a library to persist and get nodes and its relations in Redis, using different data structures depending on your need.

Hari(user: 23).out(:follow).out(:activity).limit(25)

The query above will return the top 25 activities from all nodes user 23 follows.

Relations

Creating a relation can be as simple as:

Hari.relation! :follow, user, event

# where user / event are:

- objects with #id method (node representation will be class#id, like user#23)
- strings with node_type#node_id
- hash like { node_type => node_id }
- a Hari::Node instance
