With most systems, trying to run a database of any significant size requires specialized knowledge, both to build your app and to manage the database it runs on top of. MongoDB makes your first 100GB simple - from running the database to writing the code. As your database gets larger, though, it helps to understand more about how MongoDB works so you can get the most out of it. MongoHQ has noticed that their customers that reach 100GB are running commercially successful businesses. MongoHQ recommends going through the 100GB Scaling Checklist as you grow. Watch the webinar recording on the subject for the full overview:
Identify your data behavior: Figure out how your data patterns and how they are working within your application. You will need to link your data to how your application accesses this data. Consider the simple queries and the more complex queries you will need to look up, like multi-range queries.
Refactor your schema to simplify queries
Remove data that does not fit MongoDB: remove “unrefactorable” data
Separate hot and cold data
Don’t lean on mongodump’: this disrupts RAM and causes performance issues. Consider other Backup options instead, like MMS Backup
Check your gauges: Monitor, monitor, monitor. Even if you aren’t having performance problems, set this up now so you can keep a history of your
Avoid queries causing page faults: MongoHQ has run benchmarks against this to prove this. A system running in memory that was running at 7,000 operations per second was cut down by 50% to 3,500 operations per second when adding 1% table scans churning on a disk.
Buying time with hardware: Don’t get addicted to buying hardware. Before making a purchase, always consider optimization and investigate separating and pairing data.
