This sample workflow demos how to use query API to get the current state of running workflow.

query_workflow.go shows how to setup a custom workflow query handler

query_workflow_test.go shows how to unit-test query functionality

Steps to run this sample:

1. You need a Temporal service running. See details in README.md
2. Run the following command to start worker

go run query/worker/main.go

3. Run the following command to trigger a workflow execution. You should see workflowID and runID print out on screen.

go run query/starter/main.go

4. Run the following command to see current workflow state on the screen.

go run query/query/main.go

5. You could also specify the query type "__stack_trace" to dump the call stack for the workflow.

go run query/query/main.go -t __stack_trace
