@alamb I can take a stab at this. Just want to get some feedback first: - The `FileStatisticsCache` will need to be a trait with a `list_entries` type function to get the cached entries, just like `FileMetadataCache`. Since `FileMetadataCache` is public, it will cause breaking changes, but it shouldn't be difficult to migrate. - In your example there is a `statistics_size_bytes`, but I don't think that information is directly available in `Statistics`, unlike with the cache metadata entries. However, looking at the `Statistics` struct it appears to only store two `Precision<usize>` + five `Precision<usize | ScalarValue>` per column stored, which should be relatively small. -- This is an automated message from the Apache Git Service.
