KnoxShellTable mean, median, and mode methods
URL: https://github.com/apache/knox/pull/163#issuecomment-539393241
> > Another idea: once you added `long` support you may consider `Date` or
`Timestamp` columns using `getTime()`. What do you think?
>
> @smolnar82 I could see this being useful with finding `mode,` but not
quite sure how the rest of the methods here would lend themselves to a
date/timestamp. `Max` and `min` could also be useful but I would think that
would be more of `sort` thing where you would want the table itself displayed
in order with max/min on respective ends of the table. Are there any specific
use cases you had in mind? This might be going over my head. Filing a separate
JIRA might be a good idea for this.
I believe selecting the `min` and `max` date/timestamp is very useful and
frequently used in applications dealing with those data types (e.g. give me the
last time John logged in). It's true that the same can be achieved with sorting
(ascending/descending) and selecting the first element from the result. I'll
create a new JIRA.
