Guidewire Workqueue

Guidewire WorkQueues

WorkQueues in Guidewire are used to manage and process large volumes of tasks asynchronously. They help in distributing the workload across multiple servers, ensuring efficient processing without overloading any single server.

How WorkQueues are Used

1. Task Distribution: WorkQueues distribute tasks across multiple servers, ensuring balanced load and efficient processing.

2. Asynchronous Processing: Tasks are processed in the background, allowing the main application to continue functioning without delays.

3. Scalability: They enable the system to handle large volumes of tasks by scaling the processing across multiple servers.

Gosu Code Implementation

Here's a basic example of how to implement a WorkQueue in Guidewire using Gosu:

1. Create a New Typecode: Define a new typecode in `BatchProcessType` typekey.

```gosu

<typecode name="MyNewCode" desc="Description of MyNewCode">

  <categories>

    <category name="Schedulable"/>

  </categories>

</typecode>

```

2. Create a WorkQueue Class: Extend `WorkQueueBase` to create your custom WorkQueue class.

```gosu

class MyWorkQueue extends WorkQueueBase<Message, StandardWorkItem> {

  private final static var _batchProcessType = BatchProcessType.TC_MYNEWCODE

  construct() {

    super(_batchProcessType, StandardWorkItem, Message)

  }

  override function findTargets(): Iterator<Message> {

    return Query.make(Message).select().iterator()

  }

  override function processWorkItem(p0: StandardWorkItem) {

    var bean = extractTarget(p0)

    // Your processing logic here

  }

}

3. Register the WorkQueue: Register your WorkQueue class in `work-queue.xml`.

<work-queue workQueueClass="example.MyWorkQueue" progressinterval="600000">

  <worker instances="1" batchsize="5"/>

</work-queue>

4. Schedule the WorkQueue: Optionally, register the new `BatchProcessType` in `scheduler-config.xml`.

<ProcessSchedule process="MyNewCode">

  <CronSchedule minutes="*/10"/>

</ProcessSchedule>

This setup ensures that your WorkQueue is properly configured to handle tasks asynchronously, improving the overall performance and scalability of your Guidewire application¹.
