> bq. Also, the parameter 'size' in the API
> "/containerlogs/$containerid/$filename" and similarly in AHSWebServices is
> confusing with semantics. I think we are better off with an offset and size.
> An offset (in bytes, +ve to indicate from the start and -ve to indicate from
> the end) together with a size (in bytes) indicating how much to read from the
> offset are a better combination - this is how most file-system APIs look
> like, for comparison.
> I can also imagine number of lines as a better unit than bytes for offset and
> size - perhaps yet another ticket.
