Hi Samuel! There is issue with patch about it: https://issues.apache.org/jira/browse/COUCHDB-1202
And there is the explanation why so: > One other issue: currently I haven't yet implemented commonjs for > reduce functions. The reason I have not is that reduce functions are > not batched, so library code would have to be sent and eval'd every > single time the reduce function is run. On top of this, 99% of the > time the reduce function won't make use of the library code, so it > will just be dead weight. (I have a hard time thinking of when a > reduce function will need to require library code). http://mail-archives.apache.org/mod_mbox/couchdb-dev/201009.mbox/%3CAANLkTi=hfvb8__ssfqtfzykv3e-h0odcduqazmtve...@mail.gmail.com%3E Hope they make things clear (: -- ,,,^..^,,, On Thu, Apr 4, 2013 at 5:44 AM, Samuel Williams <space.ship.travel...@gmail.com> wrote: > Hi, > > I've implemented a Ruby query server. > > I wanted to have libraries available to reduce functions. > > Is it okay to have add_lib add libraries to both mapper context and reduce > context? > > The method of loading libraries seems a bit cumbersome in the current > implementation, reducers are treated quite differently from mappers.
