Thank you for reporting this issue.

The error message indicates that the MySQL database you are using has a constraint on the rpc_port column, and the value specified in your configuration file is out of range.

Could you please check your development-mysql8.yaml configuration file and verify the rpc_port setting for the Frontend service? The default port is 7233.

If you have customized the port, please ensure that it is within the acceptable range for your MySQL database. You can refer to the MySQL documentation for information on the allowed range for port values.

If the port value is within the allowed range and the error persists, please provide the following information:

• The exact version of MySQL you are using.
• The contents of your development-mysql8.yaml configuration file.

This will help us to diagnose the issue more effectively.

Temporal 102: Exploring Durable Execution with Python

This course will take you beyond the basics of Temporal application development and equip you with the skills needed to confidently navigate the full Temporal development lifecycle. You will learn how to effectively test, debug, deploy, and update your Temporal applications.

Key topics covered:

• Testing and debugging: Learn how to write unit tests for your Workflows and Activities, utilize Temporal's Event History for debugging, and understand the various error messages that you might encounter.
• Deployment: Explore best practices for deploying your Temporal applications in a production environment, including containerization using Docker and deployment on Kubernetes.
• Workflow updates: Grasp the concepts of workflow versions and how to handle changes to your workflow code while maintaining backward compatibility.

By the end of this course, you will be able to:

• Apply Temporal best practices to develop reliable and efficient applications.
• Write automated tests to validate your workflows and activities.
• Debug workflow execution using Temporal's Event History.
• Prepare your application for production deployment using Temporal's tooling.

Prerequisites:

• Basic understanding of Temporal concepts: You should be familiar with fundamental concepts like Workflows, Activities, and the Temporal execution model. We recommend completing the Temporal 101 course with Python beforehand.
• Python programming proficiency: Knowledge of Python syntax, data structures, and object-oriented programming is essential.

What you'll need:

• A local development environment: Set up a Temporal service (using Temporal CLI or Docker) and install the Python Temporal SDK.
• A text editor or IDE: Choose a tool that supports Python development (e.g., VS Code, PyCharm).

Thanks for reporting this issue. It looks like you are experiencing a 22003: Out of range value for column 'rpc_port' at row 1 error. This error generally means that the rpc_port column in your MySQL database is too small to store the value that Temporal is trying to write. You should verify that the rpc_port column is set to a size that can accommodate Temporal's port value ( 7233, by default). Refer to https://dev.mysql.com/doc/refman/8.0/en/numeric-types.html to learn how to change a column size. If you continue to see this error, please provide your Temporal configuration file development-mysql8.yaml for review.

Estimated time: ~⏱️ 4 hours, self-paced.

Cost: Free

Description ​

In this course, you'll go beyond the basics of Temporal application development, acquiring skills that will help you on your journey to production deployment. Along the way, you'll encounter several common problems faced by Temporal developers, find out why they occur, and more importantly, how to identify and solve them, as well as how to avoid them in the future. By emphasizing key concepts and best practices, you'll gain a deeper understanding of how Temporal works and how to use it effectively.

When you've completed the course, you'll be able to:

• Apply Temporal best practices for application development
• Validate application behavior through automated testing
• Evaluate an Event History to debug problems with Workflow Execution

Prerequisites: ​

To be successful in this course, you should have an understanding of the fundamental concepts, tools, and techniques used to develop and execute basic Temporal applications with the TypeScript SDK. This includes the ability to develop and execute Temporal Workflows and Activities, navigate the Web UI, configure and run a Worker, as well as an understanding of the high-level interactions between the Temporal Application and Temporal Cluster during Workflow Execution. We strongly recommend that you complete Temporal 101, which covers these topics, before starting this course.

Since code used in examples and exercises are written in TypeScript, you must also have at least basic proficiency with the TypeScript programming language.
