[jira] [Updated] (OAK-1312) Bundle nodes into a document

["Chetan Mehrotra (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/OAK-1312?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Chetan Mehrotra updated OAK-1312:
---------------------------------
         Labels: performance  (was: docs-impacting performance)
    Description: 
For very fine grained content with many nodes and only few properties per node it would be more efficient to bundle multiple nodes into a single MongoDB document. Mostly reading would benefit because there are less roundtrips to the backend. At the same time storage footprint would be lower because metadata overhead is per document.

Feature branch - https://github.com/chetanmeh/jackrabbit-oak/compare/trunk...chetanmeh:OAK-1312
