> [REST] Rip out "transform" feature

> The 'transform' feature, where REST can be instructed, via a table attribute,
> to apply a transformation (e.g. base64 encoding or decoding) to a (sub)set of
> column values before serving them up to a client or storing them into HBase,
> was added some time ago at the request of Jack Levin. I have since come to
> regret it, it was not a well thought out feature:
> - This is really an application concern.
> - It adds significant overhead to request processing: Periodically a
> HBaseAdmin is used to retrieve the table descriptor, in order to scan through
> table attributes for transformation directives.
> I think it is best to rip it out, its a real problem area, and REST should be
> no more concerned about data formats than the Java API.
> I doubt anyone uses this, not even Jack. Will need to follow up with him to
> confirm.
