There was a problem hiding this comment.
We need to pass in the TableMetadata to have knowledge about the PartitionSpecs. I would prefer to not have to do this. There is a discussion on the Rust side here: apache/iceberg-rust#1328 (comment)

Rationale for this change
This replaces the Cython implementation for reading Avro with Iceberg-Rust. This would greatly simplify the PyIceberg project since we don't have to publish Python wheels anymore.
Are these changes tested?
Are there any user-facing changes?
