fabianmenges opened a new pull request #3438: Feature: Implementing incremental search for a column values 
URL: https://github.com/apache/incubator-superset/pull/3438
 
 
   This is the current fitler UI.
   ![currentfilter](https://user-images.githubusercontent.com/3138343/30230939-9ce9dc40-94b6-11e7-9820-2be7c44e72fb.png)
   It will pre populate all possible values. Up to a threshold, that can not be changed. If you data source contains more distinct possible values for you filter it won't load those. 
   
   This MR contains the backend for incremental search. I'm happy to make the necessary changes to the front end as well.
   
   Example:
   Searching for "me" on the "name" column of the "birth_names" datasource limited to five return values will return: 
   ![search_me](https://user-images.githubusercontent.com/3138343/30231085-3d0a4192-94b7-11e7-85a2-9b2ba291db62.png)
   Searching for "mel" will return:
   ![search_mel](https://user-images.githubusercontent.com/3138343/30231089-3e88aad6-94b7-11e7-8432-936bb2644a6e.png)
   The idea is that you make async calls to query for the possible filter values while the user is typing.
