> Reporter: netease-datastream
>
> I hava installed the phoenix and do a simple test.
> A very simple table has four columns: userid,butterid,filtertype,time
> I have import 80G data into this table.
> I run the sql
> select userId,sum(filtertype) from test group by userid
> It cost more than two minutes and the squirrel has throw timeout exception.
> I see you performance test is very quickly.
> But this test is too slow.
> I wonder if there is my config fault or others.
