That’s why it’s essential to implement the best practices and strategies for MongoDB database backups. Why are MongoDB database backups important? Regular database backups are essential to protect against data loss caused by system failures, human errors, natural disasters, or cyber-attacks.

Remote calls are never free; they impose extra latency, increase probability of an error, and consume network bandwidth.

These principles reduce resource usage by being more efficient and effective while lowering the end-to-end latency in data processing. Other than these principles, there are some other design considerations to support and enable: Multi-tenancy with database and table prioritization. Transparency to end-users. More processing resources.

The main reason behind this is that MySQL is a relational database system (RDBMS), and any data that is going to be written in it must respect the RDBMS rules. Normally this solution requires a full code redesign and could be quite difficult to achieve when it is injected after the initial code architecture definition.

Sadly, data on latency is harder to get, even from Google's perch, so progress there is somewhat more difficult to judge. One subtle effect of browser attempts to avoid showing users blank white screens is that optimisations meant to hide latency from users may cause misattribution by users in cross-site flows.

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms.
