Jackie-Jiang opened a new pull request #4051: Fix the race condition for real-time inverted index reader
URL: https://github.com/apache/incubator-pinot/pull/4051
 
 
   When getting doc Ids from RealtimeInvertedIndexReader, the given
   dict Id might not be added to the inverted index yet. We first add
   the value to the dictionary. Before the value is added to the
   inverted index, the query might have a predicate which matches the
   newly added value. In that case, the given dictionary Id does not
   exist in the inverted index, and we return an empty bitmap.
   
   Simplify BitmapBasedFilterOperator because getDocIds() never
   returns null.
   Add a test for the change.
