Re: Column Family per User

that would be 12,000 rows per day…with the maximum column size of 180M columns. Am I grasping this concept properly? Trevor Francis On Apr 18, 2012, at 3:06 PM, Dave Brosius wrote: > > Your design should be around how you want to query. If you are only querying > by user, then ha
