What is data complexity scenario for Performance testing of Data Center app?

As an Atlassian Marketplace Vendor, my company attempts to pass the Atlassian Data Center compatibility requirements documented here, and we are stuck with a requirement that we are unable to interpret.

Detail the performance results of each hardware and data complexity scenario for the actions that other systems or services can have with your Data Center App (API Definition).’

What is meant here by ‘data complexity scenario’?
Please provide us with details of required steps we should take to verify the data complexity scenario? How given data complexity scenario could be measured to identify that the requirement is reached?
Could you please provide some examples of data complexity scenarios?
Where could I find a documentation on data complexity scenario mentioned above?

Thank you in advance,
