Why and How We Migrated from Sidekiq to Temporal

Vantage transitioned from using Sidekiq to Temporal for handling its background job processing due to the increasing scale and complexity of its operations, which required enhanced reliability, scalability, and debuggability. Sidekiq, a Redis-dependent job processor, was initially effective but struggled with complex ETL tasks and job orchestration, leading to challenges like race conditions and lack of state management. Temporal, on the other hand, offers durable, stateful workflow execution with automatic retries and better visibility into job progress and dependencies, making it ideal for Vantage's needs. The migration process was divided into learning and implementation phases, where Vantage adopted an incremental approach, ensuring no downtime for customers. Temporal's architecture supports scalability and simplifies handling long-running, complex workflows, providing improved orchestration, error handling, and the ability to manage job dependencies more effectively. This shift has enhanced Vantage's internal engineering operations and improved its capacity to support its customer base by ensuring efficient ETL processes.
