---------------------------------

             Summary: [Rust] [DataFusion] Table trait should support building 
complete queries
                 Key: ARROW-5945
                 URL: https://issues.apache.org/jira/browse/ARROW-5945
             Project: Apache Arrow
          Issue Type: New Feature
          Components: Rust, Rust - DataFusion
    Affects Versions: 0.14.0
            Reporter: Andy Grove
            Assignee: Andy Grove
             Fix For: 1.0.0


DataFusion 0.13 included a preview Table trait, which provides a DataFrame 
style method of building a logical query plan, but it was not usable for any 
real-world queries.

I would now like the trait to support building real queries, especially 
aggregate queries.
