Hi Sébastien,
Awesome work! I can't wait to forward mail to Apache Kylin mailing
list. Hope you will not mind:-)
First of all, contribution to Apache community not only mean code, you
already did a great contribution to Kylin. I would like to say thanks to
you:)
Could you please help document a little bit more detail? How about you
pull request such article to Kylin's "how to" docs, or even blog?
There are many people are asking about Mondrian/Pentaho and Kylin
integration and facing some issues, you experience is definitely valuable
reference. If you could join our mailing list and help to others to
smooth their evaluation will be perfect. People are looking forward for
your experience very much:)
Back to your MDX part, it's exactly some requirements are looking for.
Do you mind to pull request your work to Apache Kylin once you have some
progress, or draft some documents about how to make it work, so that your
project could benefit entire community?
BTW, I created one JIRA for this, please leave further comments there:
https://issues.apache.org/jira/browse/KYLIN-776
Other contributors also could help you to enrich this feature.
For your talk, please feel free to refer to our latest deck:
