All taps developed using the SDK will automatically support
discovery as a base
capability, which is the process of generating and emitting a catalog that describes the
available streams and stream types.
The catalog generated is automatically populated by a small number of developer inputs. Most importantly:
Tap.discover_streams()- Should return a list of available “discovered” streams.
Stream.schema_filepath- The JSON Schema definition of each stream, provided either directly as a Python
dictor indirectly as a
Stream.primary_keys- a list of strings indicating the primary key(s) of the stream.
Stream.replication_key- a single string indicating the name of the stream’s replication key (if applicable).
