Handle Large Input/Output Data with Groovy IDE

This solution works with the Groovy IDE desktop edition.

You can use a wrapper processData_wrapper method to avoid UI performance issues. On the Groovy IDE, you can use this wrapper method, and on the Cloud Integration tenant you can just use processData method.

It works for both input and output data. Remember to remove it in the wrapper. Also, if you are working with properties and don't need the data after this script step, you can remove it in the processData method. You will save some memory for the rest of the flow.

You can use the same solution for dynamic data. For example, you can call an HTTP service and use the response as an input body or property.

We are using input_data_folder property to avoid including this developer-machine-specific detail to integration flow in the tenant.


Try it on Groovy IDE
import com.sap.gateway.ip.core.customdev.util.Message;

def Message processData_wrapper(Message message) {
    String folder = message.getProperties().get("input_data_folder");

    String fileContents = new File(folder + 'toobig.input.property_file.orders.json').getText('UTF-8')
    message.setProperty("orders", fileContents);

    String fileContents2 = new File(folder + 'toobig.input.property_file.deliveries.json').getText('UTF-8')
    message.setProperty("deliveries", fileContents2);

    // You can also write large body or property to file 
    def outputFile = new File(folder + 'toobig.output.property_file.orders.json')

    // Delete large output to avoid UI issues
    message.setProperty("orders", "removed");
    message.setProperty("deliveries", "removed");

    return message;

def Message processData(Message message) {
    // Develop your usual method.
    return message;
