Subject [jira] Created: (LUCENE-2735) First Cut at GroupVarInt with FixedIntBlockIndexInput / Output
Date Tue, 02 Nov 2010 18:06:25 GMT
First Cut at GroupVarInt with FixedIntBlockIndexInput / Output
--------------------------------------------------------------

                 Key: LUCENE-2735
                 URL: https://issues.apache.org/jira/browse/LUCENE-2735
             Project: Lucene - Java
          Issue Type: Improvement
          Components: Index
    Affects Versions: 4.0
            Reporter: Simon Willnauer
            Priority: Minor
             Fix For: 4.0


I have hacked together a FixedIntBlockIndex impl with Group VarInt encoding - this does way
worse than standard codec in benchmarks but I guess that is mainly due to the FixedIntBlockIndex
limitations. Once LUCENE-2723 is in / or builds with trunk again I will update and run some
tests. The isolated microbenchmark shows that there could be improvements over vint even in
java though and I am sure we can make it faster impl. wise.
