> I'm having second thoughts about the ChunkReader interface. I personally think the `ChunkReader` interface is good enough as is and this PR has been hanging out for quite a bit. By adding more sophistication (FromStart, FromEnd) you may save an S3 or other object store` metadata request to get the length in theory, but I suspect most applications will already have the length metadata from other sources anyway (e.g. because they had to list the objects for some other reason) so acquiring the length may not be as expensive as it first appears. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
