@felix0097 I am requesting your review but if you don't want to comb through the code changes that's fine. Please have a look at the docs/API changes and just make sure you're comfortable with them.

Looks good to me now!

To keep track this were the items we discussed:

• Only support use_collection for now that the user isn't able to do weird stuff
• Check if removing sample_rows function hurts performance for dense data -> if yes, potentially add it back in
• By default, yield var as well

Check if removing sample_rows function hurts performance for dense data -> if yes, potentially add it back in

#25 but let's wait for #101 to reimplement this much more simply

By default, yield var as well

#109

Only support use_collection for now that the user isn't able to do weird stuff

With one collection? yes that's in the implemention
