Join operators behaviour #256

Closed NicoLaval closed 5 months ago

NicoLaval commented 1 year ago

At this point, we only perform joins for same shape datasets.

DS1:

Id_1 Id_2
1 1
1 2
2 1

DS2:

Id_2 Me_1
1 X
2 Y

DS := left_join(DS1, DS2); would give:

Id_1 Id_2 Me_1
1 1 X
1 2 Y
2 1 X

Missing using

DS := left_join(DS1, DS2 using Id_2);
