iilyak opened a new pull request #1586: Improve cleanup_index_files
URL: https://github.com/apache/couchdb/pull/1586
 
 
   ## Overview
   
   The previous implementation was based on a search using
   
       {view_index_dir}/.shards/*/{db_name}.[0-9]*_design/mrview/*
   
   This wildcard includes all shards for all indexes of all databases.
   This caused performance issues in the case when there are thousands of databases on the node.
   This PR changes the search to look at index_directory of a database.
   
   
   ## Testing recommendations
   
   ```
   make && make eunit apps=couch tests=mrview_cleanup_index_files_test_
   ```
