looks like we're waiting for apache/iceberg-rust#1328 to finalize, which is dependent on apache/iceberg-rust#1482 :)

@Fokko This is awesome! thanks for your work on this one. |

@yogevyuval Thanks for asking, and yes, I do expect performance impact since just a part of the deserialization is cythonized. With this change, much more is pushed into Rust. This will also reduce the GIL pressure since we don't have to build the readers anymore :) I left this PR small to focus on the essentials, but once this is in, we can also clean up a LOT of code 👍 |
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?
