Summary: Improve couch_btree:chunkify logic
Key: COUCHDB-3298
URL: https://issues.apache.org/jira/browse/COUCHDB-3298
Project: CouchDB
Issue Type: Improvement
Components: Database Core
Reporter: Paul Joseph Davis
The current chunkify has problems when reduce functions create large values in
that it will produce chunks (ie, kp nodes) that contain a single key. In some
pathological cases this can create long chains of nodes that never branch.
The old chunkify would also try and create nodes with an even number of bytes
in each chunk. Given that we don't re-use chunks it makes more sense to try and
pack our chunks as close to the threshold as possible so that we're creating
fewer branches in our tree.
