tsbs_run_queries about Clickhouse SQL has a bug about double-groupby-xxx #278
Description
From the readme document, we can see:
So, if there are 100 devices, the data should be hoursnumber of devices,
while 100devices and 12h, result rows that should be 10012 = 1200 rows.
But origin sql will make it be 100rows (because ANY INNER JOIN)
SELECT
hour,
hostname,
mean_usage_user, mean_usage_system, mean_usage_idle, mean_usage_nice, mean_usage_iowait
FROM
(
SELECT
toStartOfHour(created_at) AS hour,
tags_id AS id,
