Overview of this book

FastAPI is an Asynchronous Server Gateway Interface (ASGI)-based framework that can help build modern, manageable, and fast microservices. Because of its asynchronous core platform, this ASGI-based framework provides the best option when it comes to performance, reliability, and scalability over the WSGI-based Django and Flask. When working with Python, Flask, and Django microservices, you’ll be able to put your knowledge to work with this practical guide to building seamlessly manageable and fast microservices. You’ll begin by understanding the background of FastAPI and learning how to install, configure, and use FastAPI to decompose business units. You’ll explore a unique and asynchronous REST API framework that can provide a better option when it comes to building microservices. After that, this book will guide you on how to apply and translate microservices design patterns in building various microservices applications and RESTful APIs using the FastAPI framework. By the end of this microservices book, you’ll be able to understand, build, deploy, test, and experiment with microservices and their components using the FastAPI framework.

Summary

In this chapter, we looked at various ways to manage data using MongoDB. We utilized MongoDB to store non-relational data for our online book reselling system since we expect the data to become large when information is exchanged between the book buyers and resellers. Additionally, the details involved in the transactions are mainly strings, floats, and integers, which are all order and purchase values that will be easier to mine and analyze if they’re stored in schema-less storage.

This chapter took the non-relational data management roadmap for utilizing the data in sales forecasting, regression analysis of book readers’ demands, and other descriptive data analysis forms.

First, you learned how the PyMongo and Motor drivers connect the FastAPI application to the MongoDB database. After understanding the nuts and bolts of creating CRUD transactions using these drivers, you learned that ODM is the better option for pursuing MongoDB connectivity. We explored...
