Just want to check— the SDK docs claim that the SDK will fully handle the override of a primary key via a stream-map override, including transforming them etc. The tap developer only needs to add two items to the tap config:

stream_maps

and

stream_map_config

. Based on my read of that part of the docs, I’d expect that, with a tap that has those config options, I should be able to: • make a new column

col_a

via stream_maps, • override the incremental key of that stream to be

col_a

, by setting

_"__key_properties__": ['col_a']

, and then • load that table incrementally (on

col_a

, since it’s overridden to be the incremental key). Is that correct? Or am I misunderstanding the SDK’s features?
