Taskflow example

You can add multiple data integration tasks to a taskflow and run them sequentially or in parallel.

The following example shows how to create a taskflow to run two

mapping

tasks in parallel. The example assumes that you know how to create a connection, a mapping, and a

mapping

task.

This example uses the following sample

mapping

tasks:

mapping

task that maps a flat file database to a flat file database.

mapping

task that maps a MySQL database to a flat file database.

Perform the following steps to create a taskflow and monitor the progress of the taskflow:

From the top menu bar, select

Data Integration

Click

New

Taskflows

Taskflow

Create

Select

Start

and enter the following General properties:

Property	Value
Name	Taskflow2MT
Location	Click Select and browse to the location where you want to save the taskflow.
Description	Taskflow to run two mapping tasks in parallel

The image shows the General properties of a taskflow.

For this use case, you do not need to enter

Notes

properties.

Drag a Parallel Path step onto the canvas.

You see a Parallel Path step with two branches.

To add Data Task steps, drag Data Task steps from the left pallette to each branch of the Parallel Path step.

Select the first Data Task step and then perform the following steps:

Go to

Properties

Data Task

and click

Select

. You see a dialog box with a list of

mapping

tasks. Select the task you want to use in the first Data Task step and then click

Select

Go to

Properties

General

and enter a name for the Data task step in the

Name

field.

Repeat the preceding step for the Data Step in the second Parallel Path branch.

Select the Parallel Path step and go to

Properties

General

, and enter a name for the step in the

title

field.

Go to

Parallel Path Properties

Parallel Paths

. You see that the Taskflow has set path 0 and path 1 of the Parallel Path step:

The image shows the parallel path properties section with branch one populated with the first mapping and branch two populated with the second mapping.

Click

from the upper-right corner of the page.

The following image shows the complete taskflow:

The image shows the complete taskflow that runs two mapping tasks in parallel.

If you do not see any validation errors, click

Run

If you see validation errors, use the Validation panel to trouble shoot the taskflow.

To verify that the taskflow is complete, check the
