Subject Digg's data model
Date Fri, 19 Mar 2010 19:16:28 GMT
I am a newbie to bigtable like model and have a question as follows. Take
Digg as an example, I want to find a list users who dug a URL and also want
to find a list of URLs a user dug. How should the data model look like for
the queries to be efficient? If I use the username and the URL for two rows,
when a user digs a URL, I will have to update two rows so I need a
transaction to keep data consistent.

Any thoughts?
