I wonder if we can eventually replace this portion with rust -- unsure what that implementation supports currently but would be fun to try it out https://github.com/apache/iceberg-rust/tree/main/crates/iceberg/src/inspect |

yep thats the goal eventually. I also think the biggest perf bottleneck is reading the avro metadata files. Once we move that part to rust (apache/iceberg-rust#1328), Im curious to see how much the entire process improves. |

Should help with apache#2130 and apache#2132 Modifies `Table.add_files` to explicitly use `inspect.data_files` and also parallelize `inspect._files` I didn't see anywhere else where looping over manifest entries was parallelized, so seems better to parallelize across manifests than within. No changes here but should be faster. --------- Co-authored-by: Kevin Liu <kevinjqliu@users.noreply.github.com>
