[jira] Created: (COUCHDB-530) reduce_overflow_error on a view
without reduce
reduce_overflow_error on a view without reduce
----------------------------------------------
Key: COUCHDB-530
URL: https://issues.apache.org/jira/browse/COUCHDB-530
Project: CouchDB
Issue Type: Bug
Components: Database Core
Affects Versions: 0.10
Environment: Ubuntu 9.04
Reporter: Miki Tebeka
This view used to work on 0.9.1, I've installed 0.10.0 and migrated some data.
When running the view I get the following error:
(env2.5)[11:47] admin $curl 'localhost:5985/stats/_design/stats/_view/active'
{"error":"reduce_overflow_error","reason":"Reduce output must shrink more rapidly: Current output: '[[25,17,117,25,93,17,13,13,12,24,14,13,10,15,20,12,14,14,17,36,38,83,18,11,1058,12,10,29,13,12,10,14'... (first 100 of 1395 bytes)"}
What's interesting is that this view does not have a reduce function. The map function is:
function (doc) {
if (doc.Type == 'max active') {
emit(doc.Time, doc.Count);
}
}
A typical document looks like:
{"_id":"02c94bea2900686a01ebbf8829aabfa2","_rev":"1-cccb3b5eb382bf609bd41feb85af063b","Count":2,"Type":"max active","Time":1254362400.0}

-------------------------------------
Yes, there are other views in the same design who do use reduce. I'm attaching the design.
Come to think of it, the problem started when trying to access another view in this design, can't remember exactly which.

Paul Joseph Davis commented on COUCHDB-530:
-------------------------------------------
I don't think it was an error in 0.9.1 and its possible to disable that check in the config.
One thing that we have said before is the ability to make views return errors and warnings to the user from view building but the current setup makes that somewhat difficult currently.
Also, that error is a bit wonky with the list vs binary confusion. I'll put it on the list to fix.

Just saw your comment.
1. I think the error can be more helpful.
2. I still don't understand how it works with 0.9.1 on the same data.

Is there another view in the same design doc that does have a reduce function? I've never seen a report of that error being triggered accidentally and your view doesn't do anything that should cause it.

Paul Joseph Davis resolved COUCHDB-530.
---------------------------------------
Resolution: Invalid
Assignee: Paul Joseph Davis
Oh there it is.
In the "duration_by_day" view the reduce function is doing "return Array.concat.apply(Array, values);" which will most assuredly break the reduce limit. Remember that when you build a view CouchDB is building all views in the same design doc, so the errors will be reported for any of the views in that doc.

> When running the view I get the following error:
> (env2.5)[11:47] admin $curl 'localhost:5985/stats/_design/stats/_view/active'
> {"error":"reduce_overflow_error","reason":"Reduce output must shrink more rapidly: Current output: '[[25,17,117,25,93,17,13,13,12,24,14,13,10,15,20,12,14,14,17,36,38,83,18,11,1058,12,10,29,13,12,10,14'... (first 100 of 1395 bytes)"}
> What's interesting is that this view does not have a reduce function. The map function is:
> function (doc) {
> if (doc.Type == 'max active') {
> emit(doc.Time, doc.Count);
> }
> }
> A typical document looks like:
> {"_id":"02c94bea2900686a01ebbf8829aabfa2","_rev":"1-cccb3b5eb382bf609bd41feb85af063b","Count":2,"Type":"max active","Time":1254362400.0}
