Thanks @omerhadari for raising this. To support this feature, there are some blocking issues since iceberg-rust's expression following java's implementation is quite limited, so it's a little difficult to do it in the core crate. I think an easy way to do this would add a transform to convert `to_data(ts) = '2025-01-01'` to `to_data(ts) = '2025-01-01' and ts >= '2025-01-01 0:00:00' and ts < '2025-01-02 0:00:00'`, and `ts >= '2025-01-01 0:00:00' and ts < '2025-01-02 0:00:00'` could be pushed down to help pruning and already supported by iceberg. There are other long term solutions to support more scalar functions, but it requires another design. -- This is an automated message from the Apache Git Service.
