We started thinking seriously about deploying Cassandra in production around three weeks ago. After looking at the site for something that would be a good fit, we settled on green badges. These badges appear on the Digg icon for a story when one of your friends has dugg it. This has been a problematic feature to support as we’ve grown, and corners had to be cut to keep it from breaking. They’re disabled on large pages (such as top in 365) and highly digg stories.

Non-relational data stores reverse this model completely, because they don’t have the complex read operations of SQL. The model forces you to shift your computation to the writes, while reducing most reads to simple operations – the equivalent of
SELECT * FROM `Table`.
