Sure, why not. Let me post a question.

I can see the need from user perspective. Let me look again at the query
parsing logic and see if any tweak is possible.

Hi chunen
It's great if you could open source your related work! I'm not sure how you
guys implemented your kylin-tools (which sounds very functional), however I

shall we drop by the Cassandra community and ask them if they have a plan
to support coprocessor-like feature? this is quite normal requirement, and
should not be too difficult for them, HBase was not born with coprocessor,
I believe.

How about one setting value when user pickup "DistinctCount"? We already
have error range, it should be easy to have one more option say "Precise"

You’re right, I ignored that can’t get return type from query context.
I’m not familiar with Calcite UDF, do you mean a new sql writing like “count
(distinct_precise seller_id)”? That’s not transparent for user, seems not the
best way.
Another way is still mapping count distinct query to one ag

I've considered exactly the same point. It does not work when mapping a
query to the aggregation functions. A query will simply say "count
(distinct seller_id)", and won't mention any return type.
The way out is adding a new aggregation for your count distinct using

Not for the core team at least. Cassandra lacks of a CoProcessor equivalent

However it is highly welcome if some one want to do a Proof of Concept in

What Marek described is as designed (an early design though, and we can
discuss if the design makes sense).
Out of simplicity, Kylin 1.x requires all segment be continuous and there's
no gap in between. So a new incremental segment always starts from where
the last segment ends. I agree the Rest

Em.. do need more document.
The "Cube Size" under the advanced setting affects the MR job
configuration. Under KYLIN_HOME/conf, you can have optional job_conf xml
for particular size of cube.

It’s really great job, Yang!
I have a question about the MeasureTypeFactory. In the current 2.x-stating
code, two built-in measure types (hll and topn) were registered, and the
factory create the corresponding MeasureType only by funcName (‘COUNT_DISTINCT’
for hll and ‘TOP_N’ for topn).
