Groww Engineering built a resilient order management system for trading using Temporal workflow orchestration. The team overcame initial skepticism by designing extensible SDKs that handle complex order types like OCO (One-Cancels-Other) and bracket orders. The architecture leverages Temporal's durability guarantees, deterministic execution, and automatic retry mechanisms to ensure zero data loss in millisecond-sensitive trading scenarios. Key innovations include self-healing orders through async procedures, configurable activities with flexible retry policies, deterministic ID generation for replay safety, and workflow versioning for risk-free canary deployments. The system eliminates traditional challenges like manual state machines, race conditions, and scattered retry logic while maintaining extensibility through strategic design patterns.
