> I set small queue to allow only 1 concurrent query:
> alter system set `exec.queue.enable`=TRUE;
> alter system set `exec.queue.small`=1;
> When running 2 small queries, one of them is pending which is expected.
> (See pic 1)
> ​After about 5mins(exec.queue.timeout_millis), the pending SQL starts. now we have
2 queries running in small queue. 
> (See pic 2)
