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:
- 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.
- 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.
- 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.
