Assert shape

Introduction

You can use the assert shape is typically used for testing purposes -you can define a static payload which is used to validate that the current payload (i.e. the payload generated up to the point that the assert shape is encountered) is as expected.

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.

To configure an assert shape, all you need to do is paste the required payload and save the shape for example:

An **assert** shape can only be saved if a payload is present. If you add an **assert payload** shape but don't have the required payload immediately to hand, you can just enter `{}`and save.
