Implement a Patch Management System for Database Updates

[Codycody31]

Overview:

We currently handle database migrations using Knex.js, but there's a need for a more robust system to manage data updates and modifications that occur after specific migrations. I propose the implementation of a Patch Management System to efficiently handle these post-migration data transformations.

Goal:

The primary goal is to create a system where we can define and execute data patches associated with specific database migrations. This will help in maintaining data integrity and consistency throughout the database's evolution.

Proposed Solution:

• Patch Class: Develop a Patch class that encapsulates the logic for each data patch. This class should include methods for applying, reverting, and checking if the patch has been applied.

• Patch Manager: Implement a PatchManager class responsible for managing the application and reversion of patches. It should register patches and apply them in association with their respective migrations.

• Database Integration: Integrate the patch system with the existing Knex migration workflow. Ensure that each patch is applied after the completion of its associated migration.

• Patch Tracking: Add a patch table to the database to track the applied patches. This table will record the patch name, the associated migration, and the timestamp when the patch was applied or reverted.

Considerations:

• Ensure that each patch is idempotent to avoid issues if a patch is run multiple times.
• Develop a robust error handling and rollback strategy for the patch system.
• Thorough testing in a development environment before deployment to production.
