> Hey @omerhadari Thanks for working on this. Unfortunately, I'm afraid that this is a pretty complex task. > > When we do like `to_date(ts)` in SQL, that maps to an Iceberg partition transform `day(ts)`. What we do in Java, we convert the `to_date(ts)` into [an UnboundTransform](https://github.com/apache/iceberg/blob/main/api/src/main/java/org/apache/iceberg/expressions/UnboundTransform.java). This transform will be bound to the schema at some point. When you do: `to_date(ts) >= 'date' 2021-01-01` the evaluator sees that it is both a date, and it can compare it directly against the partition values. Does it make sense to create an issue for supporting UnboundTransform here? -- This is an automated message from the Apache Git Service.
