What is the structure level limit for parent and child relationships when using the TreeSave REST resource?

When using the TreeSave REST resource in Salesforce, the structure level limit for parent and child relationships is capped at 5 levels deep. This means that you can have a hierarchy or structure that consists of one parent and up to four additional levels of children, making a total of five levels.

This limit is significant because it ensures that data structures remain manageable and performance can be optimized. As the depth of the relationship increases, the complexity of the data retrieval and manipulation can also increase, which can lead to performance issues. By setting a limit to 5 levels, Salesforce provides a balance between the ability to model complex relationships while also maintaining system efficiency.

Understanding this limitation is crucial for architects who are designing data models and integrations, as it will impact how data flows between systems and how records are related in your Salesforce org. It also informs developers about how to design user interfaces and queries in a way that stays within these constraints to ensure smooth operation.
