One way to debug an application is through logs. They can be used to identify issues, understand the execution flow, and also monitor the application’s behavior. Among their types, database query logs are very useful for understanding what is happening with queries and other write operations.

Benchmark testing in programming is the act of efficiently comparing performance between algorithms in order to choose which approach to follow in certain scenarios. We can also apply when deciding which external libraries or frameworks to use, in addition to evaluating if any refactoring will bring harm to our code. The Go language already has tools for these types of tests by default, making the experience more user-friendly and without the need for external tools.

After years relying on Community drivers like mgo and globalsign/mgo, last year MongoDB announced they were building it’s own solution. Last March they released the version 1.0.0, so let’s see how to make some normal operations using the Oficial driver. First of all, you need to download the driver using go get. go.mongodb.org/mongo-driver/mongo Assuming your MongoDB installation is using the default setting, your method should be like this: package main import ( "context" "log" "go.
