Unit tests increase how fast you write code because you can mock all of your dependencies, set the expectation for your function, and iterate until you get the desired transformation; however, we need more. All of these integration points require different layers of testing.

One of the common ways to classify database workloads is whether it is “read intensive” or “write intensive”. In other words, whether the workload is dominated by reads or writes. There are different “levels” of reads and writes for you to consider. Analyzing read/write workload by counts. Why should you care?

Prevention of rollbacks can be achieved by configuring appropriate write concerns, specifically ‘MAJORITY’, and enabling journaling to ensure write operations are durably acknowledged by the majority of nodes in a replica set, thereby upholding data consistency. One of the major risks is data loss which may occur as a result.
