-=== ESQL: INLINESTATS
-This adds the `INLINESTATS` command to ESQL which performs a STATS and
-then enriches the results into the output stream. So, this query:
-
-[source,esql]
-----
-FROM test
-| INLINESTATS m=MAX(a * b) BY b
-| WHERE m == a * b
-| SORT a DESC, b DESC
-| LIMIT 3
-----
-
-Produces output like:
-
-|  a  |  b  |   m   |
-| --- | --- | ----- |
-|  99 | 999 | 98901 |
-|  99 | 998 | 98802 |
-|  99 | 997 | 98703 |
