We have used MongoDB on
several production and play
projects over the last year.
We love it. MongoDB is now
the default database for
new projects at Collective
Idea.

BSON, GridFS, Map-Reduce
❖ Durability
replication scenarios, production environments
❖ Performance
mmap, indexing, concurrent requests
❖ Roadmap search, single-server durability

We currently have a manual failover
setup with a single master and slave.
The master has 72GB RAM and the
slave is in a different DC. Given disk
space limits, we are in the final stages of
migrating to using automated replica
pairs with manual sharding across 4
database servers [...]

PostgreSQL as well. Slowly

39. let MongoDB be a result of a larger effort
Find a cause

40. don’t make this mistake.
MongoDB is not a feature

41. proven causes

Displaying a photo submission form
now requires a single lookup. [...] In a
relational database, embedded
documents would typically be stored
across several tables, requiring
expensive joins. But in a NoSQL store,
embedded documents are surprisingly
efficient and yet let us apply a structure
to the data.
