Description
I am using influx 2.7 v2 version with influx query. I have a scenario where I need to get min, max values of last 10 records. Query that I was using
select min(*) from "testapis" order by time desc limit 10; Shown as below
here are my last 10 records
select * from "testapis" order by time desc limit 10
Do we have a way to address this ? or is there a work around ?

Research direction
Start by reproducing the two InfluxQL queries against InfluxDB 2.7 and compare how ORDER BY, LIMIT, and min(*) are evaluated. Determine whether the aggregate is expected to operate on the limited records, then document the supported behavior or workaround; the issue names no source files or tests to begin with.
