Worked on improving database reliability in the mojaloop/iac-modules repository by addressing issues with primary key enforcement in the mcm database. Focused on stabilizing deployments by disabling the sql_require_primary_key setting within the Kubernetes configuration and introducing a configurable parameter to manage primary key behavior. This approach centralized primary key policy management, reducing deployment failures related to database schema enforcement across different environments. The work involved updating YAML-based infrastructure as code modules and refining database configuration practices. By resolving a persistent bug, the changes enhanced maintainability and consistency for teams deploying the mcm database using Kubernetes and infrastructure as code workflows.
