thanks! I'll take a look at it. I use elasticsearch for adhoc querying : http://daemon.co.za/2012/05/elasticsearch-5-minutes/ http://daemon.co.za/2012/05/elasticsearch-5-minutes/ And couchdb does have atomic in-place updates, http://wiki.apache.org/couchdb/Document_Update_Handlers http://wiki.apache.org/couchdb/Document_Update_Handlers I used the latter recently to track the last view-time on images, as well as to build a schema migration routine in like 100 lines of code. edit fixed link
