Hi, I'm playing with the filter replication. So my filter is: function(doc, req) { if (doc.type && doc.type == 'user' && doc.userId == req.query.userId) { return true; } else { return false; } } This is to replicate all document from a given user. (This is not a continuous replication) The replication fails because of a changes_timeout error. (same error with 1.1.0 and 1.0.2) I check the code, and it seems that the pb comes from: src/couchdb/couch_rep_changes_feed.erl All timeout are hardcoded, and one of them is 10s. the request filter took between 10 and 25s. Am I doing something wrong ? Or is this a bug ? Thanks, Benoit
