Reduce end-user latency and accelerate Temporal Workflows
Feb 12, 2025

Summary
This post details the Eager Workflow Start (EWS) feature, an optimization that reduces workflow startup latency by enabling direct interaction between the client and a local worker, bypassing some Temporal Server operations. It explains how EWS provides the initial workflow task in the start response when a local worker is ready, making it beneficial for short-lived workflows and those using local activities deployed near the Temporal Server. The post also touches on the limitations of the current EWS implementation.
