Subject [jira] Commented: (JCR-2407) Make the disk space used by cached binary properties configurable
Date Wed, 25 Nov 2009 12:58:39 GMT

    [ https://issues.apache.org/jira/browse/JCR-2407?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12782402#action_12782402

Thomas Mueller commented on JCR-2407:
-------------------------------------

> The fact that we now use only a single database connection is the core

>From what I heard the main reason for the temp file was to detach SharedItemStateManager
from the persistence manager / blob store.

Again, the problem only occurs when using the blob store (unless I'm wrong). We want to deprecate
the blob store anyway, right? So would it make sense to change the blob store implementation
once database connection pooling is implemented?

> Binary properties which are in Jackrabbit's caches (SharedItemStateManager eg) are stored
on disk in the temp dir. This can cause problems on small temporary file systems as the size
of the binary properties on disk is not limited by Jackrabbit. There is one way to influence
this indirectly: make the Jackrabbit cache sizes smaller (via the CacheManager). It could
be helpful in some cases if an upper bound on the disk usage can be given.
