Jukka Zitting commented on JCR-2407:
------------------------------------

> I don't think the problem is related to database connection pooling.

The fact that we now use only a single database connection is the core reason for why we need to pull the full binary already during the PersistenceManager.load() call instead of streaming it to the client directly from the database.

We can sort why the temp files are not being reclaimed earlier without involving connnection pools, but we do weed them if we want to avoid the temp files entirely.

> 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.
