TODO: Define your stream schemas

Your connector must describe the schema of each stream it can output using JSONSchema.

The simplest way to do this is to describe the schema of your streams using one .json file per stream. You can also dynamically generate the schema of your stream in code, or you can combine both approaches: start with a .json file and dynamically add properties to it.

The schema of a stream is the return value of Stream.get_json_schema.

Static schemas

By default, Stream.get_json_schema reads a .json file in the schemas/ directory whose name is equal to the value of the Stream.name property. In turn Stream.name by default returns the name of the class in snake case. Therefore, if you have a class class EmployeeBenefits(HttpStream) the default behavior will look for a file called schemas/employee_benefits.json. You can override any of these behaviors as you need.

Important note: any objects referenced via $ref should be placed in the shared/ directory in their own .json files.

Dynamic schemas

If you'd rather define your schema in code, override Stream.get_json_schema in your stream class to return a dict describing the schema using JSONSchema.

Dynamically modifying static schemas

Override Stream.get_json_schema to run the default behavior, edit the returned value, then return the edited value:

def get_json_schema(self):
    schema = super().get_json_schema()
    schema['dynamically_determined_property'] = "property"
    return schema

Delete this file once you're done. Or don't. Up to you :)
