Subject [jira] Commented: (JCR-2051) Disk based transient space
Date Wed, 01 Apr 2009 14:15:13 GMT

    [ https://issues.apache.org/jira/browse/JCR-2051?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12694536#action_12694536

Marcel Reutegger commented on JCR-2051:

> if the ItemState is gc'ed because it is no longer externally referenced), the changes
> be lost since the  serialized copy on disk does not reflect the changes made after it
> created.

right. that part is missing in my proposal. but it can be solved by registering an item state
that gets callbacks when an item state changes. If the callback is for a weakly referenced
item state,
then the serialized copy needs to be updated.

>            Reporter: Marcel Reutegger
>            Priority: Minor
> Currently the transient space in jackrabbit-core is held completely in memory. This limits
the number of items that can be part of a save call. The memory usage for the transient space
should be lowered significantly, e.g. by writing item states to a swap file on a disk.
