Hello,
When Kylin runs in sandbox mode, is the only difference around
authentication ? Just that its a different fixed username / password
instead of using ldap etc.
Are there more differences than that for running kylin in sandbox mode

Hello,
We plan to upgrade to Kylin 1.5.x series from 1.2 series. We want to ask
the team a few questions / clarification before proceeding. Since we are
looking at upgrading, please do let us know the behaviour for the latest
1.5.x release.
1) Updating facts

Sorry for the delayed response.
what's the cardinality of the dimension that you want to count distinct
values?
--> We might be coming across different types of cardinality for the
measure. Though unsigned int capacity should cover almost all cases, there
might be some cases we miss.
For example
We have a use case where we want to rebuild the cube with an updated data
set without downtime on requests
Lets say we have cube C1.
We get some new data and we rebuild the cube.
Lets call this C2 with the new data. (Assume no change to cube structure)
When C2 is building, we want C1 to be still
the comments, it said we cast long to int.. wont we be
losing data due to truncation ?

Hello,
Is there a way to ask Kylin to get exact distinct count ? From what we
understand, we can choose between hllc(10) to hllc(16)
I understand that for every cuboid, you will need to go through the
whole data set again, but with the new cubing algo (2.x branch) should be
simpler to add
Hello,
When we purge the cube, the hbase table in which all cuboids are being
stored is not being dropped.
And as per the site seems like its a conscious decision.
http://kylin.apache.org/docs/howto/howto_cleanup_storage.html
Why dont we disable+drop the hbase table right away when w

Hello for one of the dimensions it started giving the following error and
the response was empty.

- Can't get dictionary value for column DIM_FKEY (id = 23561
Hello,
Is there a document explaining the assumptions for incremental builds.
Is it purely additive ? Lets say category id is one my row key
components. I had 10 products on category id 20. Now I got a new product
for same category would it add up. Would distinct count also be fine ?
Do
Congrats!
