Apache Druid supports "multi-value" string dimensions. These are generated
when an input field contains an
array of values instead of a single value (e.g. JSON arrays, or a TSV field
containing one or more `listDelimiter`
-characters).

indexes should be created for the column in generated segments. Creating a
bitmap index requires more storage, but speeds up certain kinds of filtering
(especially equality and prefix filtering). Only supported for `string` typed

Possible values are `sorted_array`, `sorted_set`, and `array`. `sorted_array`

duplicates. `array` ingests data as-is | `sorted_array` |
Review comment:
It'd be nice to link "multi-value fields" to the
`../querying/multi-value-dimensions.md` doc, so these two pages cross-link to
each other.
