> Project: ORC

> Reporter: Mithun Radhakrishnan

>
> 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.
