[jira] Resolved: (JCR-773) Under heavy load, database journal may
contain empty update records.
[ https://issues.apache.org/jira/browse/JCR-773?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dominique Pfister resolved JCR-773.
-----------------------------------
Resolution: Fixed
Problem identified: on some occasion, the temporary file's contents was not written to disk even after closing the FileOutputStream. Remedied by syncing on its file descriptor.
Introduced a performance optimization, using in-memory records as long as size stays under a certain limit.
Fixed in r513340.
