"A user's data is stored in a single row in HBase"

Some column families of HBase can be accumulated to hundreds of mega bytes very easily, I'm afraid...

I'm really surprised to learn that they use Haystack here.

That's really cool for both Haystack and Django.

I think you're thinking of this: http://haystacksearch.org/

Ahhh... yes. thanks.

I was wondering what they were using as an indexer :-)
