Subject Jackrabbit Workspace Configuration in Clustered Mode
Date Mon, 23 Apr 2012 21:41:57 GMT
Hello, we currently have a clustered Jackrabbit configuration using a
FileDatastore stored on a SAN via NFS and PostgreSQL as the
PersistenceManager shared amongst the nodes.  Currently, it looks like most
of the storage is being used in the database and not the datastore,
particularly the ws_bundle table is taking up a huge amount of space.  I
thought that our repository configuration should have put all of the files
in the datastore based on the Jackrabbit Wiki pages, but perhaps I am
missing something.  Here is my repository.xml file I'm using with comments
etc removed for brevity:

<?xml version="1.0"?>

Does anyone know what I'm missing?  Should each persistence manager include
a DataStore element?  I could not find examples with that in it, but
evidently the workspace is storing most of the content in the database, and
not the datastore.  Note that almost all the nodes are relatively large
documents (> 100K ) and should definitely be smaller than the *
minRecordLength* I have set as a property.
