Apache Pinot

Hi all, I wanted to confirm whether multiple columns can be specified as `sortedColumn` in a table spec?  The docs[1] certainly seem to indicate that this might be possible, but I’m not certain.  Follow up question if the answer is “Yes”:  if I were to _add_ a second column to a table with an existing `sortedColumn` config and reload segments, would that cause the newly added second sortedColumn to take effect?

[1] <https://docs.pinot.apache.org/basics/indexing/forward-index#sorted-forward-index-with-run-length-encoding>

The answer was in the docs (above link) all along:

> ```Additionally, for online tables, even though this property is specified as a JSON array, at most one column should be included. Using an array with more than one column is incorrect and will not result in segments being sorted by all the columns listed in the array.```
