GraphQL - Return the Size of an Array Field?

@matthewmcneely - follow up question -

Do you know if it’s possible to filter or otherwise query on a Lambda predicate? I just tried a query using a filter on the visit_count predicate and get the message:

Field \"visit_count\" is not defined by type Guest.

I’m thinking this is going to require a Lambda Query but just wanted to confirm that this is expected behavior.

Thank you
