Robert Muir commented on LUCENE-4765:
-------------------------------------
For the disk codec I did a simple solution of writing the entire ordinal stream
as block-packed on disk.
The indexes to this stream are loaded into memory (MonotonicBlockPacked). I
think this is a pretty good tradeoff
that might work reasonably well for this codec: we can always think of
alternative encodings.

> The general idea is basically the docvalues parallel to

> Currently this stuff is used in e.g. grouping and join for multivalued
> fields, and in solr for faceting.
