10 Minutes advanced

Ensure timely trigger processing by creating a dynamic pool of workers to handle requests

From this lab, the user will use a cluster of workers to handle a set of WorkOrders in parallel. Business ROI: Dynamic job processing provideds a scalable, general purpose way to automate routine tasks

Summary¶

Create Cluster of workers¶

From the Clusters view, click Add Set Name to lab3060

Set `Required Params` `broker/name` to `context-broker`

Click `Save`
```
1. Wait for cluster to complete building

Put Cluster Machines in WorkOrder mode¶

Go to the Machines view
Select all machines that start with "lab3060-"
Hover over the Actions dropdown and select Work Order Mode All machines should enter WorkOrder mode and show pending/running Work Orders in the table.

Update lab3010 Trigger¶

Go to lab3010 editor
Change Filter to cluster/tags:In:lab3060
Set Queue Requests to false
Under Work Order Config, add a parameter, dev/wait-time with a value of 1 Click a white space area to make sure all items are saved

Distribute and Run Work Orders¶

Go to the Machines view

```
In the Queue Requests `false` mode for the trigger, the Work Orders are assigned when they are created.

Go to lab3010 editor
Set Queue Requests to true

Queue Work Orders to the Machines¶

Go to the Machines view

Noitce the lab3060-* machines having pending and running work orders The Work Orders are distributed to all machines and each machine will run a Work Order order from the queue when it can. This cause lets the work distribute to the machines based upon their availablity.
Let the Work Orders complete All machines should have '0's showing for pending and running Work Orders.
