Subject Re: Is my Use Case possible with Hive?

how many # records?

what is your hadoop cluster setup? how many nodes?
if you are running hadoop on a single node setup with normal desktop, i

You need a stronger cluster setup for better query runtimes and ofcourse
query optimization which I guess you would have already taken care.
