PascalPuchtler opened a new issue #1137: Execution of queries takes a lot of time
URL: https://github.com/apache/couchdb/issues/1137
 
 
   In my database I like to run requests data over a view. After the Request the database takes a long time to update the index, but the index has no changes. This takes about 6 minutes.
   When the index is ready the execution of the reduce step takes about 1 minute.
   
   ## Expected Behavior
   The index schoul only update if changes happened or should be everytime up to date.
   The request should execute faster.
   
   ## Current Behavior
   The index updates when no changes happened.
   The request should execute very long.
   
   ## Possible Solution
   No Idea.
   
   ## Steps to Reproduce (for bugs)
   Its not so easy, because of the "big" amount of data.
   
   ## Context
   **Request:**
       "ids": {
         "map": "function (doc) {    emit([doc.Header.Serialnumber, doc.Header.Parameter, doc.Header.Time],1);  }",
         "reduce": "_count"
       }
   
   **Data:**
   The size of the database is 5GB with 100k documents.
