---------------------------------
Hi Richard,
First, I have no idea if my answer brings any offence, hope you could
understand that's explanation about the current status. And I have said it's
"valid" request to have such feature if there are many people really want it.
Actually, I have had a call with Aleksey last week, author of Olaper, to
discuss about this project and possible way to figure out the synergy between
these two projects. As our conversation, it's still young and doing same way
like Mondrian: transfer MDX to underlying SQL, like MySQL and others, and then
leverage Saiku to do the UI part, for their customers. So Kylin could be
another source if someone could contribute.
So you already could try with Olaper to interactive with Kylin, just like
Mondrian way. As the ecosystem we are building today, people are free to do
that.
But for "The idea would be to include the Olaper code-line and use it to
generate Cubes Query interface for XML/A directly in Kylin", I don't think
it's good idea to copy code without author's permission or even just notify
author. It will better to have it to be one dependency library:-)
As an open source project, everyone could contribute their idea, code and
even testing result, would you mind to have a try and let community to know if
there's any issue?
I also sent this JIRA to Aleksey, maybe he could have more idea.
Thanks.

> XML/A for Kylin

> Key: KYLIN-1525

> Issue Type: New Feature
> Components: Query Engine
> Reporter: Richard Calaba

> It would be great if Kylin can be accessed also by standard OLAP tools
> supporting XML/A so native OLAP queries can be addressed by Kylin.
> I have seen somewhere on the Internet the option to use Pentaho Mondrian with
> some Kylin-patch to achieve this. However I found much simpler solution
> open-sourced here - https://github.com/Wondersoft/olaper .
> The idea would be to include the Olaper code-line and use it to generate
> Cubes Query interface for XML/A directly in Kylin. Kylin knows both - the
> logical structure of the Cube and the storage structure - that's excatly what
> is needed for Olaper to make it work - you need JDBC Driver and then a 2
> metadata files (cube.json and table.json) to describe to the Olaper the
> logical and physical cube structure ...
> I believe that would be very powerful extension opening Kylin to other OLAP
> UI tools (like Saiku i.e.). Today we just rely on Tableau UI consuming Kylin
> through ODBC driver.
