Warnings During Property Graph Creation

When creating a property graph, the property graph wizard validates the designed graph and reports any validation errors or warnings.

It is important to note that you can still create a property graph by ignoring the warnings that are generated at the time of creating the graph. However, the graph cannot be loaded into memory.

The following table lists the warning messages that are generated during property graph creation.

Warning Message Reason
Vertex table <table_name> has composite key (<composite_key>) which will prevent this graph from being loaded into memory.

See the documentation for more details
