答复: show the kylin sql for timeout
Hi, yunyao.
Is that you mean you want to see the phenomenon of SQL query timeout? Why do you want to do that? Or you just want to know the value of timeout?

At present, Kylin's min "kylin.query.timeout-seconds" is 60s, and you can
not set this smaller.
If you want to simulate the scenario of timeout, you can take a look at
"ITKylinQueryTest#testTimeoutQuery". It uses a hack way, see:
"org.apache.kylin.gridtable.StorageSideBehavior#SCAN_FILTER_AGGR_CHECKMEM_WITHDELAY".
But I do not recommend this cuz it seems just for developing and it is too
hacky.
By the way, Kylin's timeout exception is: KylinTimeoutException. And
there's a test mocked this scenario:
"org.apache.kylin.rest.service.KylinQueryTimeoutTest". May this can help
you.
