In this chapter, you saw that besides thinking of our schema design based on our queries, it is also important to think about the planning of the operation and maintenance for the creation of our collections.

You learned how to use tag sets to deal with datacenter-aware operations and why we limit the amount of documents stored in our collections by doing a capped collection. In the same manner, you saw how TTL indexes can be useful in real-life use cases.

In the next chapter, you will see how we can scale our MongoDB instance by creating shards.
