Subject [jira] [Commented] (OAK-1312) Bundle nodes into a document
Date Thu, 21 Jul 2016 06:31:20 GMT

    [ https://issues.apache.org/jira/browse/OAK-1312?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15387250#comment-15387250

Chetan Mehrotra commented on OAK-1312:
--------------------------------------

As of now read and writes of such bundled node structures are working with current impl in
branch [1]. Next stuff to take care of is conflict resolution

[~mreutegg] [~catholicon] Can you have a look at current implementation and approach taken
to determine what would be the best and least intrusive way to generalize current conflict
resolution logic in DocumentNodeStore to account for such bundled document. Any pointers here
would be helpful to move further

> 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.
