Thanks alot ,
i tried to enjoy cb.incr which is atomic , when i use cb.set and then cb.incr it is less efficient as .
Thanks alot i understand the topic.
Still there is an issue , which relates to the key length , as i mentioned before .
cb.incr works great when the key is around 40 charterer length .
when i use cb.incr on a longer key around 120 length. This doc.encoding changes , to BASE64 ( and the view engine has to decode the data into utf8 which is an uwanted overhead for each Indexing operation).
