Preloaded content selection graph validation

A method, comprising:

• obtaining, by a system comprising a processor, content response data of a graph node, the content response data formatted based on client-specific information;
• obtaining, by the system, a validation rule set based on a type of the graph node and the client-specific information;
• evaluating, by the system, the content response data with respect to the validation rule set;
• and
• in response to the evaluating indicating that the response data passed the evaluating, validating, by the system, the graph node for use in a content selection graph, and
• in response to the evaluating indicating the response data did not pass the evaluating, taking action, by the system, that indicates the node has a validation violation issue.

A machine-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, the operations comprising:

• generating a content selection graph of nodes comprising response data in an in-memory data storage;
• and
• processing the content selection graph to attempt to validate the nodes, the processing comprising:
• obtaining first response data for a first node in the graph;
• obtaining a rule set associated with the first node;
• determining whether the first response data passes the rule set;
• and
• in response to determining that the first response data passes the rule set, validating the first node, and
• in response to determining that the first response data does not pass the rule set, taking action that indicates that the first node has a validation-related issue.
