Real async feature enhancements

This article describes the real async feature enhancements to SysOperations. These enhancements enable operations to be run asynchronously without blocking the client as the regular SysOperations do. Therefore, users can initiate multiple operations simultaneously. In this way, the enhancements help improve overall performance.

The status of async operations can be viewed on the same page.

To use real async operations, you must extend the SysOperationServiceController class.

For more information about the SysOperation framework, see SysOperation Framework Overview.

Enable the real async feature

1. In the Feature management workspace, select Check for updates.
2. Enable SysRealAsyncOperationsFeature.
3. After you've enabled the feature in Feature management, go to Client performance options, and select the Enable real async operations option.

Uptake the real async feature

To use real async operations, you must first extend the SysOperationServiceController class, as you normally do to implement SysOperations. Then override the following methods to enable real async operations for your service operation class.

Method 1: canRunAsRealAsync

By default, the canRunAsRealAsync method returns false.

1. To turn ON/OFF the real async execution of your operation at runtime, introduce a feature for your operation and confirm the feature is enabled inside canRunAsRealAsync method. If the main Real Async feature is enabled in Feature management, the returned value decides if the operation will be ran in real async or not.

Here's an example.

public boolean canRunAsRealAsync()
{
    if (featureManagementForSalesOrderConfirmationRealAsync::isEnabled())
    {
        // This operation can run through real async
        return true;
    }
    else
    {
        return false;
    }
}

2. Return true to run the operation in real async by default.

Method 2: getSysRealAsyncOperationId

By default, the getSysRealAsyncOperationId method returns an empty string.

• Override this new method, and return the ID of the current operation. For example, if the operation is confirming a sales order, return the SalesId value of the order.

Here's an example.

public SysRealAsyncOperationId getSysRealAsyncOperationId()
{
    Common sourceTable = this.parmSourceTable();
    str orderId;
    if (sourceTable && sourceTable is SalesTable)
    {
        SalesTable salesTable = sourceTable;
        orderId = salesTable.SalesId;
    }
    else
    {
        orderId = this.parmId();
    }
    return orderId;
}
