Subject Re: Kylin cube partitioning strategy
Date Wed, 23 Mar 2016 13:25:55 GMT
Hi Norbert,
     Typically, people are using BI tool rather than SQL client to
interactive with Kylin.
     But I think this is valid feature to make popular SQL tools also works
with Kylin.

     Forward this mail to dev@ list for more comments.

     Thanks.
Luke


Best Regards!
