    Description

      Hi,

      I read in the knowledge base that Disk-based aggregation are not implemented.

      Have you some ETA/Roadmap on this feature or is it out of the scope?

      It could be quite helpfull to avoid the process to be killed when he asks for too much memory on aggregations, especially since it's working for joins.

      Regards

      Mathieu
