Uniq node: that one dedupes the values
inside one property, this one dedupes the dated-property entries
themselves by their date and group id.
Inputs
- Data — the dated properties to deduplicate.
Output
- Result — the entries with duplicate
valid_from+idpairs collapsed to one, emitted newest first.
Notes
- Entries collapse only when they share both date and group id. Two entries with the same value but different dates are both kept.
