Stefan Egli created OAK-5602:
--------------------------------
Summary: avoid missing journal entries
Key: OAK-5602
URL: https://issues.apache.org/jira/browse/OAK-5602
Project: Jackrabbit Oak
Issue Type: Improvement
Components: core
Affects Versions: 1.6.0
Reporter: Stefan Egli
Fix For: 1.7.0, 1.8
As a follow up of OAK-5601: that one is about a situation where backgroundRead
falls way behind and journal GC cleans up journal entries before it was able to
read it. We should generally look into improving this situation, eg by having
journal GC not do the clean up as long as there are instances that haven't read
the entry. This could perhaps be achieved by periodically having each instance
inform the rest about what journal entries it has processed (or simpler: how
far back it would be find for journal entries to be GC'ed)
