> This is a duplicate of ORC-238, but it applies to {{branch-2.2}}.
> Compression buffer-sizes in OrcFile are computed at runtime, except when
> enforceBufferSize is set. The only snag here is that this flag can't be set
> by the user.
> When runtime-computed buffer-sizes are not optimal (for some reason), the
> user has no way to work around it by setting a custom value.
> I have a patch that we use at Yahoo.
