我试图从alb日志中获得每天请求url的最大点击量(吞吐量)。我使用表投影来划分表。尝试找出查询,以获得过去1-3年中所有URL每分钟最大点击量的所需结果。结果应该是这样的(只是一个示例,时间戳可以是任何格式)
timestampurlmax点击率每分钟12-29-2019 8:01 amurl11072012-29-2019 10:35 amurl22132912-29-2019 10:35 amurl33742012-30-2019 11:53 amurl1589812-30-2019 01:30 pmurl21423012-30-2019 05:19 pmurl320000
表创建查询:

您可以尝试:

with cte as (
   select date_trunc('minute',timestamp) as minute, url, count(*) as hits_per_minute from mytable
group by 1,2
)
select max_by(minute, hits_per_minute) as timestamp, url, max(hits_per_minute) from cte
group by date_trunc('day', minute), url

说明:公共表表达式( cte )将计算每个url每分钟的点击次数,然后从中提取达到最大点击次数的分钟数(使用 max_by 函数)和最大点击数,按 day 以及 url .
