There currently isn't a way to do that. What are your requirements that
would be easier with a custom codec? ORC uses the codecs in a very specific
way so that it can support indexing. By default ORC indexes each 10k rows
and the compression is done in blocks so that the reader can skip over
blocks it does not need.
