Amazon Marketing Stream Dataset Event Level Documentation

[tspicer]

Various response events across all datasets may or may not have values present for each element, which can result in NULL values. The documentation is silent on the expectations for the contents in response to the event's behaviors for each element, such as when something may or may not be present. For example, campaigned will never be NULL in response, but bidSetting.bidStrategy may be NULL if X, Y, and Z are true.

This information allows for better operational and programmatic testing. We can more quickly identify potential issues or variations and explain to end users why, under certain use cases, a given record may be NULL.
