kevinjqliu opened a new issue, #3497:
URL: https://github.com/apache/iceberg-python/issues/3497
Several `StartsWith` / `NotStartsWith` visitors appear to compare binary
values by converting them with `str(...)`, which gives incorrect byte-prefix
behavior.
Examples:
```text
StartsWith("x", b"a") on b"aa" -> False # expected True
NotStartsWith("x", b"a") on b"aa" -> True # expected False
```
This also affects planning paths:
```text
inclusive metrics for a file containing only b"aa":
StartsWith("x", b"a") -> False # unsafe skip
```
Manifest evaluation for binary `StartsWith` can also raise `TypeError` when
comparing decoded `bytes` bounds to a `str` prefix.
Relevant code: `pyiceberg/expressions/visitors.py` starts-with handling in
expression, manifest, metrics, and residual visitors.
