I get "True" when I run GET /_config/query_server_config/reduce_limit for
both- couchdb server 1.5.0 and 1.5.1.
Also, I just have a very simple design doc with 2 views. Even this doesn’t work
on couchdb 1.5.1 and works ok on cocuchdb 1.5.0
def createDesignDocForErrors():
design = db.design('errors')
resp = design.put(params={
"_id":"_design/errors",
"language": "javascript",
"views":
{
"by_test_id": {
#"map": "function(doc) { if (doc.type == 'error')
emit(doc.test_id, doc.errors) }"
"map": "function(doc) { if (doc.type == 'error')
emit(doc.test_id, doc.error_count) }",
"reduce" : "_sum"
},
#http://10.247.32.72:5984/longevity/_design/errors/_view/by_testid_starttime?group=true
"by_testid_starttime": {
"map": "function(doc) { if (doc.type == 'error')
emit([doc.test_id,doc.start_time], doc.error_count) }",
"reduce" : "function(keys, values) {return (values[0])}"
}
}
})
I can't run this view either. Says, problem accessing a view.

As Mike pointed out, you will see noticeably better performance using the
builtin function.
Do you see any errors, in particular Reduce output must shrink more rapidly or
reduce_overflow_error ?
https://couchdb.readthedocs.org/en/latest/couchapp/views/nosql.html#aggregate-functions
It’s possible you have a different config on each box, for the reduce
heuristic;
GET /_config/query_server_config/reduce_limit is what you would be looking to
compare between the boxes.
Thanks Bob & Alex for reminding me of the error messages!
A+
