Subject Re: Re: 'Grouping' documents so that a set of documents is passed to the view function

Could a better approach be to use an ETL tool such as Jasper or Pentaho to  
perform the analysis and either use them to display or load another CouchDB  
or MySQL instance for viewing the data ? I would instead opt to perform  
analysis with a Business Intelligence suite, unless the reporting solution  
needs are fairly basic, since he mentioned growth would be a factor. Growth  
could be accounted for within a Data Warehouse, separate from CouchDB, or  
kept inside it. Something to consider. But my background is in Enterprise  
architectures & scaling.
