Good morning peeps! I was wondering what the usecase was for the

is_timestamp_replication_key

flag? https://sdk.meltano.com/en/latest/classes/singer_sdk.Stream.html#singer_sdk.Stream.has_selected_descendents Is this only for development, or can it be used in production?

1. The use case for

is_timestamp_replication_key

is in order to infer if datetime math should be used in comparison login, and also to infer if timestamp-based signposts can be used relative to

utcnow()

. If the replication key is not a timestamp (meaning it is likely numeric or symbolic), then those datetime-based comparisons and signposts would be invalid. 2. The use case for

has_selected_descendents

is for determining if a deselected parent stream still needs to be invoked (perhaps silently), in order to iterate upon the selected child streams.

Yes, that's awesome! Thanks 😄
