MV_MAXedit
Converts a multivalued field into a single valued field containing the maximum value. For example:
ROW a=[3, 5, 1] | EVAL max_a = MV_MAX(a)
| a:integer | max_a:integer |
|---|---|
[3, 5, 1] |
5 |
It can be used by any field type, including keyword fields. In that case picks the
last string, comparing their utf-8 representation byte by byte:
ROW a=["foo", "zoo", "bar"] | EVAL max_a = MV_MAX(a)
| a:keyword | max_a:keyword |
|---|---|
["foo", "zoo", "bar"] |
"zoo" |
