In MongoDB, durability is not considered a top priority due to practical reasons such as the risk of data loss from hardware failures or natural disasters. The database's design focuses on replication and snapshotting instead, which provide true durability by maintaining multiple copies of data across different servers. While single server durability is still planned for the future, the current approach prioritizes horizontal scalability and minimizing downtime in case of hardware failures. This allows MongoDB to achieve 99.99% uptime, making it suitable for many web applications. The focus on replication and snapshotting enables fast recovery from failures, making MongoDB a reliable choice for data storage.
