[jira] [Created] (LUCENE-4179) bulk-compress blocktree term suffix
lengths
Robert Muir created LUCENE-4179:
-----------------------------------
Summary: bulk-compress blocktree term suffix lengths
Key: LUCENE-4179
URL: https://issues.apache.org/jira/browse/LUCENE-4179
Project: Lucene - Java
Issue Type: Improvement
Reporter: Robert Muir
these should be fairly tiny numbers, it seems wasteful to use a byte-per-term when they typically only need a few bits.
also if we have them in bulk, its a step towards random access.

[jira] [Updated] (LUCENE-4179) bulk-compress blocktree term suffix

Robert Muir updated LUCENE-4179:
--------------------------------
Attachment: LUCENE-4179.patch
patch (passes test, but not benchmarked).
i still dont like that we are making the suffix lengths larger by stealing bits for leaf/non-leaf, and we can maybe cleanup a few other things.
but first we should make sure its smaller and just as fast, or faster and not larger :)

faster (at least with 1M wiki), slightly uglier version :)
will run the 10M wiki now...
