Our company likes reports that calculate ambiguous metrics - metrics that can not be calculated with ActiveRecord's searchers (except for find_by_sql) and where the ruby ​​of Rs. Based capabilities are still very slow

Is there a plugin or gem or db adapter that will calculate large in database layer? What is your solution for creating complex reports?

If you want to use your ORM or if you are aware that the complex in ActiveRecord There is a lack of express expression for the questions you may not possibly have decided to switch from ActiveRecord, but it may possibly be possible to check at least.
