主题: Re: Apache Kylin performance problem
Hi Zhifeng,
Thanks for the sharing. A few questions for it: Is this change made in Apache
Environment
Apache kylin 1.6.0
Jdk1.8.0_72 64-Bit
any one cube and any one SQL
Problem
When the concurrency users count increase, many request’s response time
become longer and longer, but some are normal.
This is because when calcite parse the sql.
The fun
LV1,SUM(V) V,COUNT(*) C FROM TEST GROUP BY LV1
Return: LV1 VC
001 -1.0 1
the sum(v) is right.
