Great Presentation on mongoDB scaling and replication. At Phyber we use mongoDB for schema-less non-durable data storage – in other words, if the database goes bye-bye it doesn’t matter.
If you are using mongoDB, and you data is critical there are some excellent points in here.
The slides may come across as overly negative. After all Urban Airship is actively moving away from MongoDB for our largest and busiest pieces of data. So I want to make 2 things very clear:
- I like MongoDB and would like to use it again in the future. There’s a lot I don’t like about it, but I can’t think of any “perfect” piece of software.
- The IO situation in EC2, particularly EBS’s poor performance RAIDing really doesn’t help made life with MongoDB miserable. This story may have been very different if we were running MongoDB on bare metal with fast disks.
