January 2025 monthly summary for redhat-developer/rhdh-plugins. Focused on reducing complexity in the orchestrator workflow path and stabilizing the abortion flow. Implemented orchestration identifier consolidation by replacing businessKey with orchestratorAssessmentInstanceId in ExecuteWorkflowRequestDTO and ProcessInstanceDTO, enabling simpler execution and retrieval. Reverted to restore the original businessKey-based flow where needed to preserve backward compatibility. Streamlined workflow abortion by replacing the abort mutation with a direct DELETE call via SonataFlowService, improving reliability and reducing latency in abort scenarios. Collectively, these changes improve maintainability, reduce cross-component coupling, and accelerate reliable workflow termination.
