In my experience, range partitioning is usually represented with only the
partitioning points, which addresses the infinite end cap issue, and guarantees
that everything is covered. Each point is exclusive for the range to the left
side of the point and inclusive for the range to the right side of the point.
So your example would be more like:
To create three ranges (infinitely small to `2021-01-01`, between
`2021-01-01` and `2022-12-32`, and `2022-12-32` to infinitely large)
```
`[date]`: [
[2021-01-01]
[2022-12-32],
...
]
```
And the date + city example would be:
```
`[date, city]`: [
[2021-01-01, Allston],
[2021-01-01, Boston],
[2022-12-32, Allston],
[2022-12-32, NYC],
...
]
```
(or something).
