David Overton 9921823915 GDC-189 custom aggregations ... > ## Description -> This PR allows DC agents to define custom aggregate functions for their scalar types. ### Related Issues -> GDC-189 ### Solution and Design > We added a new property `aggregate_functions` to the scalar types capabilities. This allows the agent author to specify a set of aggregate functions supported by each scalar type, along with the function's result type. During GraphQL schema generation, the custom aggregate functions are available via a new method `getCustomAggregateOperators` on the `Backend` type class. Custom functions are merged with the builtin aggregate functions when building GraphQL schemas for table aggregate fields and for `order_by` operators on array relations. ### Steps to test and verify > • Codec tests for aggregate function capabilities have been added to the unit tests. • Some custom aggregate operators have been added to the reference agent and are used in a new test in `api-tests`.
