Lefty Leverenz commented on ORC-238:
------------------------------------

Mithun, this is most embarrassing ... I haven't updated any ORC documentation yet, despite many good intentions, so I don't know how it's done.  But take a look at ORC-65 for an example.

> 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.
