> This is an extension to
> [ARROW-10368|https://issues.apache.org/jira/browse/ARROW-10368].
> When reading a Parquet file, you first need to read its footer and metadata.
> If you only have "read from start" capability, this means you need the size
> of the file to read relatively to end. On some storages, getting the size
> metadata can be expensive (e.g extra http call for blob storage).
> The proposition is to add the capability to "read from end" to the
> ChunkReader trait as most file storages will have this feature (file storage
> as well as blob storages).
