In December 2024, delivered critical features and CI fixes for localstack/moto, focusing on DSQL cluster management and Terraform CI reliability. Implemented the DSQL Cluster Management API with create_cluster and get_cluster endpoints, including models, backend logic, responses, and tests. Introduced input validation and creation-time/deletion-protection attributes to ensure safe cluster lifecycles. Fixed CI by configuring Terraform in the workflow to ensure environments are correctly prepared before tests, resolving failing Terraform tests. Expanded test coverage around the new API and CI changes to improve reliability. Result: improved developer productivity, system reliability, and business value through automated cluster provisioning and stable test infrastructure.
