Yordan Pavlov updated ARROW-10759:
----------------------------------
Description:
If DataFusion had support for creating date literals using a cast expression
such as
CAST('2019-01-01' AS DATE) this would allow a user-friendly way for 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.
