=== `GREATEST`
|

|

|
|
Returns the maximum value from many columns. This is similar to <<esql-mv_max>>
|
||
|
|
except it's intended to run on multiple columns at once.

NOTE: When run on `keyword` or `text` fields, this'll return the last string
|
||
|
|
in alphabetical order. When run on `boolean` columns this will return
|
||
|
|
`true` if any values are `true`.
