> Hi,
> When 40 queries are executed on kylin parallelly (at once)
> the response time distribution is as below, with min, max and mean response
> time as 6557,7580 and 6887 ms respectively.
> Kylin doesn’t seem to handle parallel execution of queries.
> !SlowQueryExecution.png!
> !SlowQueryExecution1.png!
> But when 40 queries are executed over 40 seconds i.e one
> query executed per second the response time distribution is as below, with
> min, max and mean response time as 110,2820 and 248 ms respectively.
> This seems fine as the mean response time in less than a
> second.
> !NormalQueryExecution.png!!NormalQueryExecution1.png!
>
> There seems to be some problem when queries are fired in
> parallel to kylin.Please help.
