I'm trying to do a side project where I need to store 30M+ rows of data. Tried MySQL at first just to see what would happen (tl;dr; it didn't). I'm looking at Cassandra next but it doesn't have a very robust query system. I don't need anything complex, just something to throw data at and then say I need all rows (one at a time) which have or don't have column X as null.
Regardless of that, I'm curious what you all use on various projects?
