Course content

7 sections • 12 lectures • 1h 14m total length

Introduction2:08
Scale flask APIs using Arc and Supervisor, containerize with Docker, and enable inter-process communication via a publish-subscribe mechanism for production-ready microservices; manage workers with Redis and Arc dashboard.

Flask Skeleton4:13
Create a basic Flask API skeleton with the application factory, expose a single endpoint, and prepare for asynchronous parallel processing and a job queue to handle XML sanitation.
Main Endpoint8:37
Implement the main endpoint of the Flask microservice to sanitize XML files with lxml recovery and huge tree, generating faulty samples to test performance.
Short Intermission1:26
Take a brief intermission to share your honest feedback, guiding potential students and creators and shaping Pathonic education's high-quality educational material tailored to your needs.
RQ and Supervisor16:57
Learn how to scale a flask api with redis-backed queues, workers, and supervisor to process xml sanitization tasks asynchronously, using docker compose, unique job IDs, retries, and a status endpoint.

Worker Management with Redis CLI8:39
Connect to the Redis server with Redis CLI to monitor workers and manage queues. Inspect keys, view queues and in-progress jobs, and terminate or remove specific tasks.
RQ Dashboard5:56
Integrate Arc dashboard with Flask and Supervisor to monitor and manage the sanitize queue and workers in real time, using Redisai, with configurable poll intervals and dockerized deployment.

Requirements

A foundational understanding of Flask and experience with Python programming are required, as this course is geared toward more advanced concepts in API scaling and parallel processing

Description

Unlock the Power of Scalable Flask APIs with Parallel Processing

Are you ready to scale your Flask applications and boost your backend performance? "Flask API Scaling: Parallel Processing with RQ & Supervisor" is a comprehensive course crafted to help you create responsive, high-performance Flask Microservice APIs.

Why Enroll in This Course?

Comprehensive Flask Microservice Setup: Learn how to build a modular and scalable Flask API, setting up a solid foundation for creating reliable microservices.
Efficient Task Handling with Redis Queue (RQ): Discover how to manage background processes seamlessly. By integrating Redis Queue (RQ), you'll enable parallel task execution that ensures smooth API performance, even under heavy traffic.
Streamlined Deployment with Docker: Master the deployment of your Flask applications using Docker. Containerize your microservices for consistent, environment-independent operation and simplified scaling.
Inter-Process Communication: Implement a Pub/Sub (publish/subscribe) mechanism, allowing multiple processes to communicate efficiently, making your application more modular and robust.
Advanced Worker Management: Learn to control and monitor your background tasks with Redis CLI and track real-time updates with RQ Dashboard for smooth workflow management and effective scaling.

What You'll Learn

Setting Up Flask Microservices: Develop a microservice skeleton and main API endpoints.
Task Management with RQ & Supervisor: Configure Redis Queue and manage processes with Supervisor.
Dockerized Deployment: Containerize your Flask app for easy deployment and scaling.
Inter-Process Communication: Implement custom workers and a Pub/Sub mechanism.
Worker Control & Monitoring: Utilize Redis CLI for worker management and track tasks with RQ Dashboard.
