Derrick Harris:

If you’re wondering what kind of performance and scalability requirements forced these companies to MongoDB, and then to customize it so heavily, here are some statistics:

• Foursquare:
  • 15 million users;
  • 8 production MongoDB clusters;
  • 8 shards of user data;
  • 12 shards of check-in data;
  • ~250 updates per second on user database, with maximum output of 46 MBps;
  • ~80 check-ins per second on check-in database, with maximum output of 45 MBps;
  • up to 2,500 HTTP queries per second.
• Wordnik:
  • Tens of billions of documents with more always being added;
  • more than 20 million REST API calls per day;
  • mapping layer supports 35,000 records per second.
• Disney:
  • More than 1,400 MongoDB instances (although “your eyes start watering after 30,” Stevens said);
  • adding new instances every day, via a custom-built self-service portal, to test, stage and host new games.

Add to these Viber Media numbers:

• 30 million plus registered mobile users
• 18 million active users talking 11 million minutes every day

I have an exclusive interview with Viber Media people queued up for the next days.
