Set variables shape

Introduction

The set variables shape is used to set values for flow variables and/or metadata variables at any point in a flow.

Need to know

When defining variable values you can use:

• static text (e.g. blue-003)

• payload syntax (e.g. [[payload.productColour]])

• flow variable syntax (e.g..{{flow.variables.productColour}})

A single incoming payload for any process flow shape should not exceed 500MB.

We recommend processing multiple, smaller payloads rather than one single payload (1000 x 0.5MB payloads are more efficient than 1 x 500MB payload!).

For payloads up to 500MB, consider adding a flow control shape to batch data into multiple, smaller payloads. Payloads exceeding 500MB should be batched at source.

Adding & configuring a set variables shape

Step 1 In your process flow, add the set variables shape in the usual way:

Step 2 Access shape settings:

Step 3 Click the add new variable option associated with the type of variable that you want to define - for example:

Step 4 Options are displayed for you to define the required variables and their values. How these are displayed depends on the type of variable you've chosen to add:

Variable (flow variables)

Choosing to add a variable displays a flow variable drop down field:

From here you can select any flow variable that's been defined for this process flow - for example:

You then define the required values to be applied, and confirm with the accept button:

Meta (payload metadata variables)

Choosing to add a meta variable displays key and value fields:

From here you define your variable name as the key and set the the required value to be applied - then confirm with the accept button:

Step 5 Once variables are accepted they're added to the settings panel (you can edit/delete as needed):

Step 6 Save the shape.
