Subject [Jackrabbit Wiki] Update of "Performance" by AlexanderKlimetschek
Date Sun, 14 Dec 2008 16:19:17 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Jackrabbit Wiki" for change notification.

The following page has been changed by AlexanderKlimetschek:

  A. The current Jackrabbit design is optimized for small to medium sized child node sets,
i.e. up to ~10k child nodes per node. Really large child node sets negatively affect write
performance (in the current design).
+ == Q. I have many references to a single node and performance goes down. ==
+ A. The current Jackrabbit design is not optimized for many nodes referencing a single node,
because for easy back-referencing in the JCR API all those references are stored in the target
node. Please note that many people don't recommend references in a content model anyway -
see for example DavidsModel, [http://wiki.apache.org/jackrabbit/DavidsModel#head-ed794ec9f4f716b3e53548be6dd91b23e5dd3f3a
rule #5].
