FYI while I was reviewing the code in https://github.com/apache/arrow-datafusion/blob/master/datafusion/src/physical_plan/parquet.rs in the context of https://github.com/apache/arrow-datafusion/issues/363 I noticed there is already a way to do "partial evaluation" for expressions -- maybe we could fake the same to evaluate `Exprs` that have no inputs -- pass in a 1 row null array as input or something. -- This is an automated message from the Apache Git Service.
