[jira] [Created] (ARROW-10759) [Rust][DataFusion] Implement support for casting string to date in sql expressions

Yordan Pavlov created ARROW-10759:
-------------------------------------

             Summary: [Rust][DataFusion] Implement support for casting string to date in sql expressions
                 Key: ARROW-10759
                 URL: https://issues.apache.org/jira/browse/ARROW-10759
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Rust - DataFusion
    Affects Versions: 2.0.0
            Reporter: Yordan Pavlov


If DataFusion had support for creating date literals using a cast expression such as 
CAST('2019-01-01' AS DATE) this would allow direct (and therefore more efficient) comparison of date columns to scalar values (compared to representing dates as strings and then resorting to string comparison).
I already have a basic implementation that works, just have to add some more tests.
