Building Resilient Sweep Networks with Temporal Workflows

This post details the migration of a financial institution's sweep network system to Temporal. It focuses on stabilizing SFTP operations and database-intensive tasks by wrapping them in Temporal Activities, leveraging Temporal's automatic retry mechanism for transient failures. The post outlines a phased migration approach, starting with SFTP operations, and describes how Temporal Workflows manage the orchestration, while Activities handle external interactions like SFTP uploads/downloads and database queries. It also details the integration with a legacy system, using Signals and Queries to coordinate the Temporal Workflow's execution with the existing process, and highlights the benefit of Temporal's event history for auditing and debugging.
