tilinna opened a new issue #12428:
URL: https://github.com/apache/arrow/issues/12428
I didn't find any code from v8-master using the io.Reader interface of the
`parquet.ReaderAtSeeker`. And the only usage for the io.Seeker was to find out
the size of the file.
```go
type ReaderAtSeeker interface {
io.ReaderAt
io.ReadSeeker
}
```
Therefore, I propose the interface to be simplified (and possibly renamed)
to:
```go
type SizedReaderAt interface {
Size() int64
io.ReaderAt
}
```
For example, io.SectionReader and bytes.Reader already implement this
combination, so the changes should be minimal.
Also, when converting a client-provided ReaderAtSeeker (_SizedReaderAt_)
into a io.SectionReader (in buffered reading mode), it would be a good idea to
first test whether the instance is already implementing the SectionReader API
too.
