Ownership data skew is what the consultant shoulddiscuss with the university, because it is a potential performance issue that can occur when a large number of records are owned by a single user. In this case, the Integration User owns over one million Contact records, which can cause slow or failed queries, reports, or list views. The consultant should advise the university to distribute the ownership of the records among multiple users or queues to avoid ownership data skew. API call limits, account data skew, and OAuth token limits are not relevant tothis scenario. References:
