   @houqp Indeed, I mean I could just remove the dict lookup and do it in another PR so we could just get array access here. 
   The problem is here https://github.com/apache/arrow-datafusion/pull/1006/files#diff-08a2204dc38facfa0757eed25f99d9047fcd3b44bd03df02c89f6f71afacefefR143 and here https://github.com/apache/arrow-datafusion/pull/1006/files#diff-6a157f1b320a619e7a3896027ce7d47a8e3ffeeae8ac3d21fe9157c92ebc2a6bR5218
   If there I have a column, each row may contain a dict, and so if I do a reverse lookup, then it should return a value for each non-null row right, but instead the dict is treated as a single instance.
