Mithun Radhakrishnan commented on ORC-238:
------------------------------------------
Sorry for the delay, [~leftylev]. I'm afraid I can't make out how one modifies
the documentation on the ORC page. :/
> Make OrcFile's "enforceBufferSize" user-settable.

> Key: ORC-238
> URL: https://issues.apache.org/jira/browse/ORC-238
> Project: ORC
> Issue Type: Improvement
> Affects Versions: 1.4.0, 1.5.0
> Reporter: Mithun Radhakrishnan
> Assignee: Mithun Radhakrishnan
> Fix For: 1.5.0
>
> Attachments: ORC-238.1.patch
>
>
> 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.
