Subject [jira] [Created] (COUCHDB-1791) Initial index of views is highly fragmented
Date Fri, 10 May 2013 14:41:16 GMT
James Howe created COUCHDB-1791:
-----------------------------------

             Summary: Initial index of views is highly fragmented
                 Key: COUCHDB-1791
                 URL: https://issues.apache.org/jira/browse/COUCHDB-1791
             Project: CouchDB
          Issue Type: Improvement
          Components: JavaScript View Server
            Reporter: James Howe


function(doc) {
  if (doc.a = 'b') { emit(doc._id, null); }
}

This view, running on CouchDB 1.2.1, takes 16 minutes to index from scratch on an inactive
database, creating a 2.5GB file.
After compaction, the file is then only 157MB.

Can we do something about this waste of disk I/O, such that the initial index is smaller to
start with?
