------------------------------------
Summary: Offload the node deduplication cache offheap partially
Key: OAK-4967
URL: https://issues.apache.org/jira/browse/OAK-4967
Project: Jackrabbit Oak
Issue Type: Improvement
Components: segment-tar
Reporter: Alex Parvulescu
The node deduplication cache sits by default at {{8388608}} by default [0]
which means it can grow up to {{1.6GB}} on its own. It would be interesting to
look into offloading some it the items offheap by configuration, to reduce the
effect a full compaction might have on a running instance (and possibly in
general reduce the on-heap footprint).
