I’ve been browsing through the web but haven’t been able to find any concrete topics on the integration of Saiku with Drupal. The main challenge seems to be that Saiku is java-based while Drupal runs off PHP.
I am wondering if anyone has implemented, or can provide thoughts on this union.
Is there anything similar to Saiku that would work with Drupal?
A developer of Saiku could answer you better than me but what I can say is that communication between Saiku-ui and Saiku is REST, so it is pure utilization of HTTP protocol. An integration could be an independent SAIKU server, Drupal relaying requests from the embedded UI inside your content.
Saiku is based on Mondrian, which is also a java library, but it can be deployed as an independent XMLA server. So you could recode Saiku REST services in PHP, which would call the XMLA services.
