Developed a new resource for the hashicorp/terraform-provider-azurerm repository, enabling declarative management of Azure Event Grid Namespace Topics through Terraform. Leveraging Go and Terraform, the work introduced full CRUD support for topics within an Event Grid namespace, allowing users to automate topic lifecycle operations as part of their infrastructure-as-code workflows. This addition empowers teams to build and maintain scalable, event-driven architectures on Azure by simplifying resource provisioning and management. The implementation focused on end-to-end integration with Azure APIs, ensuring seamless topic creation, updating, and deletion, and addressed a key feature request to enhance the provider’s event-driven infrastructure capabilities.
