Looks like I could have been much clearer, apologies! The main ideas around picking HLL was that it was a good compromise between fast operation, forget nothing nature of the assoc table, and avoided the should-you-really-do-that nature of storing possibly 100s of thousands or millions of numeric kvs in a hstore column alone. There’s definitely a whole ‘nother post in there on pushing it to it’s limits but it was already long enough, I thought!
