How exactly is data structured and stored into keys?

[athityakumar]

I've a feed with namespace kf and a redis instance instance $redis.

$redis.keys.select { |k| k.start_with? "kf" }.count
#=> 98

User.count
#=> 61462

Please let me know how I can access something like the result of SimpleFeed.knowledge_feed.activity(some_user_id).paginate(page: 1).map(&:value) using my $redis variable. I'm imagining something like $redis.get "appropriate key name" or something along those lines.

Please check out the part of README that talks about how to expose Redis commands that are generated by SimpleFeed.

Not having seen your code, I don't know whether $redis is even pointing to the same Redis instance as your SimpleFeed.

But assuming you are talking to the correct Redis instance, I would say that you most likely did not call store for each and every User in your table, but perhaps you called it only for those users that have generated or received an event. Users that are not receiving any events via SimpleFeed would have NO feed created for them, i.e their feed would be nil.

Hope this helps.

Below is the image that is generated by running example file with REDIS_DEBUG variable set. Note that an "appropriate key name" is not as easy to guess since it's compacted using base62 I believe.
