Add field filtering to improve network throughput #425
Description
Is your feature request related to a problem? Please describe.
Include fields query to define fields that are expected to return. This can improve network traffic by defining only the data requested (similar to GraphQL)
Describe the solution you'd like
Define re-usable getFields that can be used to filter only fields requested.
Describe alternatives you've considered
GraphQL can achieve this out of the box.
