The best request is the one that never happens: in the fight for fast websites, avoiding the network is far better than hitting the network at all. Any asset that carries the no-store directive will always hit the network, no matter what. If there is a newer file available on the server, we definitely want to download it.

Key Takeaways Rollbacks in MongoDB are triggered by disruptions in the replication process due to primary node crashes, network partitions, or other failures, which can lead to substantial data loss and inconsistencies. This failure in replication could happen due to crashes, network partitions, or other situations where failover occurs.

MongoDB is a non-relational document database that provides support for JSON-like storage. First released in 2009, it is the most used NoSQL database and has been downloaded more than 325 million times. Indexing can help to speed up read queries, but it comes with an extra cost of storage, and they will slow down write operations.
