Subject [Jackrabbit Wiki] Update of "DataStore" by ThomasMueller
Date Wed, 09 Dec 2009 14:49:35 GMT
Dear Wiki user,

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

The "DataStore" page has been changed by ThomasMueller.


  Q: What would happen when multiple users download large files from the store? A: Db``Data``Store:
It depends on whether the copyWhenReading option is enabled or not (see there). File``Data``Store:
The same file would be opened multiple times. The file would be in the operating system /
file system block cache, so that wouldn't be a problem.
+ Q: Can I change the file content in he data store? A: No. The whole point of the data store
is that the content is immutable.
  Clustering is supported if you use a shared file system, such as SAN or NFS (Windows file
sharing works as well). You need to set data store path of all cluster nodes to the same location.
  Blob Store: When the data store is enabled, the blob store is not used. The data store solves
the same (and more) problems than the blob store. Therefore, the blob store is now deprecated,
however it will be supported for quite some time.
