pymongo vs Motor

Motor is an async Python driver for MongoDB.

When should I use Motor?

You should use Motor when you're trying to interact with a MongoDB database in an asynchronous context. When you're making something that needs to be asynchronous (like a web server, or most commonly from what I've seen here, Discord bots), you also want all the database calls to be done asynchronously. But pymongo is synchronous, i.e it is blocking, and will block the execution of your asynchronous program for the time that it is talking to the database.

Okay, How do I switch now?!

Thankfully for us, switching from pymongo to Motor isn't too hard, and won't need you to change much code. This process can be roughly summarized as:

Step 1: Install Motor, and import it

Installing can be done with pip - pip install motor

Git Commit Best Practices

Basic Rules

Commit Related Changes

A commit should be a wrapper for related changes. For example, fixing two different bugs should produce two separate commits. Small commits make it easier for other developers to understand the changes and roll them back if something went wrong. With tools like the staging area and the ability to stage only parts of a file, Git makes it easy to create very granular commits.

Commit Often

Committing often keeps your commits small and, again, helps you commit only related changes. Moreover, it allows you to share your code more frequently with others. That way it‘s easier for everyone to integrate changes regularly and avoid having merge conflicts. Having large commits and sharing them infrequently, in contrast, makes it hard to solve conflicts.

Conventional Commit Messages

See how a minor change to your commit message style can make a difference.

git commit -m"<type>(<optional scope>): <description>" \
  -m"<optional body>" \
  -m"<optional footer>"
