Eager Workflow Start Sample

Eager Workflow Start (EWS) is an experimental latency optimization with the goal of reducing the time it takes to start a workflow.

When the starter and worker are collocated and aware of each other, they can interact while bypassing the server, saving a few time-intensive operations.

Here we modify the helloworld sample, ensuring that starter and worker run in the same process, and share the client. Also, the request eager mode flag is set in the start workflow options.

Steps to run this sample:

1. Run a Temporal service with eager workflow start enabled by a dynamic config value.

temporal server start-dev --dynamic-config-value system.enableEagerWorkflowStart=true

2. Run the following command to start the combined worker and example

go run eager-workflow-start/main.go
