Robert Muir commented on LUCENE-2886:
-------------------------------------
bq. Hi Michael, Robert,
great to hear that the code is useful, looking forward to see some benchmark.
I think the VarIntBlock approach is a good idea. Concerning the two unused
"frame" codes, it will not cost too much to add them. This might be useful for
the frequency inverted lists. However, I am not sure they will be used that
much.
In the case of 240 1's, i was surprised to see this selector was used over 2%
of the time
for the gov collection's doc file?
But still, for the all 1's case I'm not actually thinking about unstructured
text so much...
in this case I am thinking about metadata fields and more structured data?

> Project: Lucene - Java
> Issue Type: New Feature
> Components: Codecs
> Reporter: Renaud Delbru
> Fix For: 4.0
>
> Attachments: LUCENE-2886_simple64.patch,

>
> We could test the implementation of the Adaptive Frame Of Reference [1] on
> the lucene-4.0 branch.
> I am providing the source code of its implementation. Some work needs to be
> done, as this implementation is working on the old lucene-1458 branch.
> I will attach a tarball containing a running version (with tests) of the AFOR
> implementation, as well as the implementations of PFOR and of Simple64
> (simple family codec working on 64bits word) that has been used in the
> experiments in [1].
