Temporal Workflow Orchestration for Membership System

1 post · Dec 2024

What this trail covers

GrabUnlimited has migrated its membership system from a legacy architecture to Temporal, a workflow orchestration engine. This migration addresses challenges in scalability, concurrency, resiliency, and idempotency that arose from rapid subscriber growth. The new system uses Temporal workflows to manage membership purchases and renewals, replacing SQS and Redis locks with Temporal's built-in features like infinite retries, exponential backoff, and timers. This has resulted in an 80% reduction in open production incidents and improved membership experience.

  1. Turbocharging GrabUnlimited with TemporalThis post details the migration of GrabUnlimited's membership system from a legacy SQS and Redis lock-based architecture to Temporal. It highlights the architectural issues of the previous system, including scalability bottlenecks with cron jobs, concurrency issues due to short Redis lock TTLs, resiliency problems with upstream service outages and complex state machines, and a lack of idempotency guarantees. The adoption of Temporal is presented as the solution, leveraging its features like infinite retries, exponential backoff, and timers to manage membership purchases and renewals, leading to a significant reduction in production incidents.
