> But in this case the data is already in memory through the `load_table` operation. You're correct. By reusing the `metadata_location` and `TableMetadata`, we can eliminate 2 unnecessary network requests in this scenario. However, I have the following concerns about this change: First of all, not all catalogs are implemented in memory, which means they cannot benefit from this change. Adding `metadata_location` and `TableMetadata` to `CommitTable` could result in additional costs for every update operation. Secondly, the `Catalog` should not rely on client input. Users may inadvertently fill the `CommitTable` with incorrect metadata location or metadata. Finally, the location of users' metadata or metadata itself could be outdated. For example, the iceberg table is undergoing concurrent writes and the client's metadata location may have already been changed. I believe we should exclude `metadata_location` and `TableMetadata` from `CommitTable`. Instead, let's rely on the `Catalog` to maintain the state accurately, which will also enhance the usability of our catalog API.
