Hi
The idea that supports Kylin adding measures dynamically is impressive.
But in my opinion, once you add a measure, the existing segments should
also calculate the new measure(just add a new measure column). Users can

Seems like "incremental build"? Cube data consists of segments and
every building is a new segment and will not refresh the old segs.

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:

In my opinion, segments/partition pruning is actually in the scope of

etc. We can put all these stuff in such a system and make the separation

Hi Scott Fan,
1. Kylin only stores aggregated values in cubes, you can try to query
sum(PRICE) and see the results.
2. It's as expected, "COUNT aggregation" means count(*), it does not need a
column.

I have the impression that Kylin may return a wrong answer for the raw
query(if you do not have raw measure) but not throw an exception.

As far as I'm concerned, using Parquet as Kylin's storage format is pretty
