rnewson commented on issue #2621: GET {db}/_index endpoint response does not reflect index deletion
URL: https://github.com/apache/couchdb/issues/2621#issuecomment-593407642
 
 
   mango's "list" function lists the contents of the ddoc_cache which does not accurately represent the list of indexes. In my opinion ddoc_cache should only be used to speed up the loading of design documents on request, it's not appropriate to use it to make any claim about the current state of the database.
   
   One of two paths suggest themselves;
   
   1) change mango list to query the database for the list of ddocs 
   2) ensure there are bounds of how inaccurate the ddoc cache can get (will an index delete request trigger cache invalidation directly? are we waiting for the LRU to remove this item after a time delay or, worse, only when we hit capacity and must make space for a new ddoc?)
