QUESTION
I am using Apache drill in embedded mode and when I am able to connect to mongo and query in drill successfully.
However when I create a schema in saiku schema designer using driver as "org.apache.drill.jdbc.Driver" and URL as "jdbc:drill:drillbit=hostname:31010" the connection is successful and all collections are also fetched and shown as tables in saiku, but in place of column names "*" is coming and actual column names are not coming.
Dont know what I am missing on.
...ANSWER
Answered 2019-Apr-25 at 08:38I figured out the solution and posting in case anyone could benefit. I had created a view in drill with select * from table. When I created view as select col1,col2... from table the issue got resolved.
QUESTION
I had some conflicts with my teammates about if it is really the Power BI can read and explore Apache Kylin Cubes or it is just exploring the Data source,
I had some problems with saiku exactly in the Mondrian schema that's why I am using Power BI, I couldn't use Superset cause of the lack of time since i need to deliver the project in time.
I just want to do some data visualization from the cubes,
Is there any understandable documentation you guys can provide me? I will really be grateful for any help!
...ANSWER
Answered 2019-Apr-14 at 09:41There is no Cube API in Power BI. You could display Kylin defined tables in Power BI through ODBC driver. There are some commercial solutions for Kylin and Power BI. Check this: https://kyligence.io/resources/enable-interactive-big-data-analytics-of-power-bi/
QUESTION
could someone tell me how to share a query saiku by url? When I try it on another computer using "open in new window" url sends me to the initial screen of pentaho server. I tried using:
http://localhost:8080/pentaho/api/repos/path:mysaikuquery.saiku/run
but it disables the edit functions, and i need them.
Thank you very much in advance!! Regards

We are trying to improve the performance of a Saiku analytics server. For this, we have created aggregate tables at different granularities so that Mondrian can make use of them and retrieve the results faster.
While analyzing the logs, we have discovered that the aggregate tables are not being used by the SqlTupleReader class of Mondrian. This class has the responsibility of creating the different combinations of the dimensions in a cube.
On the other hand, Mondrian is using the aggregages successfully to retrieve data segments.
After reviewing the code and some similar cases, we have found that Mondrian 4 lacks this feature, while other versions are doing it correctly.
We were wondering if there is any version of Mondrian compatible with Saiku that supports aggregate tables to retrieve dimension tuples and, if so, how could we use this version in our instalation.
Thanks in advance for your help.

Answered 2018-Apr-03 at 11:31For anyone interested, this is the feedback I received from the Saiku team:
https://github.com/OSBI/saiku/issues/647
It seems that we won't be getting support for this feature, but we can use the workaround proposed in the thread.
QUESTION
So, I installed pentaho bi server on my debian8 server. Then managed to install saiku on it. Now, I have used workbench to make a cube and published it into the server.
Here's the problem: when I access a saiku query, I DO can load my published cube, but when I try to navigate it, that is, establishing the measure and some dimension field in both columns and rows, NO DATA SHOWS!
And I know the database is not empty, thank you very much. Here is the fact_table, if it is helpful (the dimensions have the shown id's plus their own data, of course):
...ANSWER
Answered 2017-Mar-02 at 16:36It turned out that the most recent version of Pentaho BI server is not compatible with Saiku. I installed the previous stable version and now the saiku queries show the data.
QUESTION
I'm using eslint-loader (for webpack 2) in my application, and I have this error:
...ANSWER
Answered 2017-Feb-13 at 20:22In your webpack.core.js
you define both module.rules
and module.loaders
. Although the module.loaders
is still valid, for compatibility reasons, Webpack seems to ignore it when module.rules
is present.
To solve your problem you can simply put all loaders in module.rules
. Since you're merging the two configs, you also have to update webpack.dev.js
to use module.rules
, which is also recommend by the official docs: https://webpack.js.org/guides/migrating/#module-loaders-is-now-module-rules.
