This project template illustrates the design pattern for subscription style business logic.

Setup

Run the Temporal Server:

git clone https://github.com/temporalio/docker-compose.git
cd docker-compose
docker-compose up

Start

Start the Worker:

go run worker/main.go

Start the Workflow Executions:

go run starter/main.go

This will start the Workflow Executions for 5 customers with the following Ids:

Id-0
Id-1
Id-2
Id-3
Id-4

Get billing info

You can Query the Workflow Executions and get the billing information for each customer.

go run querybillinginfo/main.go    

Run this multiple times to see the billing period number increase during the executions or see the billing cycle cost.

Update billing

You can send a Signal a Workflow Execution to update the billing cycle cost to 300 for all customers.

go run updatechargeamount/main.go

Cancel subscription

You can send a Signal to all Workflow Executions to cancel the subscription for all customers. Workflow Executions will complete after the currently executing billing period.

go run cancelsubscription/main.go

After running this, check out the Temporal Web UI and see that all subscription Workflow Executions have a "Completed" status.
