JeonDaehong opened a new issue, #3450: URL: https://github.com/apache/iceberg-rust/issues/3450
### Apache Iceberg Rust version main (1270e329b) ### Describe the bug The spec allows equality delete columns nested under structs, and `EqualityDeleteWriter` accepts them (see the nested-field test in `equality_delete_writer.rs`). But reading such a delete file fails the scan with `Unexpected => field not found`: `RecordBatchTransformer` only maps top-level field ids (`record_batch_transformer.rs:889`). ### To Reproduce Table schema `1: f long, 2: s struct<3: f long>`. Equality delete file with `equality_ids = [3]` and one row `s.f = 7`. Loading it through `CachingDeleteFileLoader` (evolve_schema, then parse) returns `Err(Unexpected => field not found)`. ### Expected behavior The delete is applied to rows where `s.f = 7`, as for a top-level column. ### Willingness to contribute I can contribute a fix for this bug independently -- This is an automated message from the Apache Git Service.
