We started a project with mongodb, at the time testing the WiredTiger engine. This engine was more interesting because it packs data much more than mmapv1. But sometimes the mongodb just falls down. So we tested mmapv1, which, despite not compressing both data and wired, solved the crash problem: mongodb did not crash. So we ended up opting to use mmapv1 anyway.
Out of curiosity: who opted for the wiredtiger engine,
- have not had problems with mongodb falling frequently?
- If yes, how did they resolve?
