Subject Re: Schema advice: (Single row or multiple row!?) How do I store millions of columns when I need to read a set of around 500 columns at a single read query using column names ?
Date Mon, 23 Jul 2012 18:00:42 GMT
For each user in my application, I want to store a *value* that is queried
by using the userId. So there is going to be one column for each user
(userId as col Name & *value* as col Value). Now I want to store these
columns such that can efficiently read columns for  atleast  300-500 users
in a single read query.
