Mailbox has grown unbelievably quickly. During that growth, one performance issue that impacted us was MongoDB’s database-level write lock. The amount of time Mailbox’s backends were waiting for the write lock was resulting in user-perceived latency. While MongoDB allows you to add shards to a MongoDB cluster easily, we wanted to spare ourselves potential long-term pain by moving one of the most frequently updated MongoDB collections, which stores email-related data, to its own cluster.
