Multi-dimensional analysis in MongoDB

Question

I was wondering is there any way of doing multi-dimensional analysis in MongoDB? Besides using a middle SQL like layer to stage the data between MongoDB and the analysis engine.

I am trying to use a Pentaho with MongoDB for BI, but I worry about how to handle Multi-dimensional analysis or even if I should try to do it at all. I know that there were some plans for Mondrian to access directly mongodb but nothing has been implemented yet.

Answer 1

In Pentaho EE 5.1 due out sometime this half of the year analyzer will have native mongo support - but that is only EE.

Your other option is indeed to use a SQL layer, and optiq is a good choice for that. The Saiku guys have got mondrian running via optiq to Mongo - and have even built support for aggregations. Note: The native Pentaho support mentioned above does NOT use optiq.

Unfortunately there's few other options at this stage!

Answer 2

how about your data type? If they are structured data and you want have SQL and OLAP capability, you could refer to Kylin OLAP which just open sourced this month: http://kylin.io/
