Redis at Digg: Story View Counts

Digg just rolled out a new feature, cummulative page event counters (page views plus clicks), that is using Redis as its underlying solution.

Clickstream information is extracted real time from logs and then Redis’s support for incrementing values comes into play. And in case you are wondering how these counters deal with concurrent updates, keep in mind that Redis is a single threaded engine, so all operations are executed sequentially.

In Digg’s own words: “Redis rocks!”
