-----------------------------
Summary: Oak sessions should be refreshed before tail compaction
Key: OAK-9321
URL: https://issues.apache.org/jira/browse/OAK-9321
Project: Jackrabbit Oak
Issue Type: Improvement
Components: jcr
Affects Versions: 1.22.5
Reporter: Jörg Hoh
Although discouraged since forever, long running JCR sessions are still seen
quite often in applications I see.
One effect of these long running sessions is that in combination with tail
compaction it can lead to SegmentNotFoundExceptions. These exceptions are not
persistent, meaning that the storage layer is not affected. A restart will
cause the SNFE to vanish until they appear again after some time.
Of course fixing the long running sessions is definitely the right way to fix
this problem, but it'S unlikely that it can be fixed easily in all cases.
Therefor I would propose to have a workaround, which refreshes all open
sessions (older than 1h?) before performing tail compaction. It would be great,
if the sessions would be logged, which are refreshed, so it can serve as input
for the fixing.
