Summary

Temporal is a robust tool for building reliable systems, but latency can be a hurdle when rapid user feedback is crucial, particularly in applications like e-commerce. Techniques such as the Early Return pattern and Local Activities can significantly reduce latency by splitting workflows into immediate and background tasks, enhancing responsiveness without compromising durability. The Early Return pattern allows for synchronous quick responses while continuing longer tasks asynchronously, potentially reducing latency by up to 50%. Local Activities, which operate within the same process as the workflows, can further cut down execution time by eliminating the need for round-trip calls to the Temporal Service. Additionally, combining Early Return with Local Activities can reduce workflow response time by as much as 91%. The Eager Workflow Start technique further optimizes speed by executing workflows locally without the matching delay, showcasing how these methods can be mixed to achieve improved efficiency. These strategies demonstrate how Temporal workflows can be optimized to fit latency budgets, ensuring quicker user interactions while maintaining system integrity.
