What issue is commonly associated with lookup skew in Salesforce?

Lookup skew typically occurs when one record has many related child records through a lookup relationship, causing an imbalance in the hierarchy of data. This situation can lead to significant challenges, particularly when it comes to data integrity and the management of relationships between records.

When records need to be updated or saved, lookup skew can create issues because the parent record may have too many child records associated with it. This can lead to confusion in processes that involve cascading updates or triggers. For instance, if a parent record is deleted or its related child records are altered, it could result in data discrepancies or failures in automated processes that rely on these relationships. Therefore, it is essential to handle lookups carefully to avoid complex dependency problems that arise during data manipulation.

The other options do not accurately reflect the primary consequences of lookup skew. They do not address the inherent challenges of maintaining data integrity and the risks associated with updating skewed relationships within Salesforce.
