Subject [jira] [Created] (OAK-210) granularity of persisted data
Date Fri, 27 Jul 2012 12:12:34 GMT
Stefan Guggisberg created OAK-210:
-------------------------------------

             Summary: granularity of persisted data
                 Key: OAK-210
                 URL: https://issues.apache.org/jira/browse/OAK-210
             Project: Jackrabbit Oak
          Issue Type: Bug
          Components: mk
            Reporter: Stefan Guggisberg


the current persistence granularity is _single nodes_ (a node consists of properties and child
node information). 

instead of storing/retrieving single nodes it would IMO make sense to store subtree aggregates
of specific nodes. the choice of granularity could be based on simple filter criteria (e.g.
property value).

dynamic persistence granularity would help reducing the number of records and r/w operations
on the underlying store, thus improving performance.
