-----------------------------------
Summary: StandbyClientSyncExecution uses an unbound segment cache
Key: OAK-5465
URL: https://issues.apache.org/jira/browse/OAK-5465
Project: Jackrabbit Oak
Issue Type: Bug
Components: segment-tar
Reporter: Francesco Mari
Assignee: Francesco Mari
Priority: Blocker
Fix For: 1.5.18, 1.6
{{StandbyClientSyncExecution}} uses a cache to avoid loading a {{Segment}} from
the primary instance if it was already loaded before. This cache is simply an
unbounded {{HashMap}}. In case a lot of segments are written on the primary
instance (e.g. during compaction), this cache puts too much load on the standby
instance - possibly resulting in out-of-memory errors.
