----------------------------------
Summary: Properly handle tail compactions in deduplication caches
Key: OAK-6519
URL: https://issues.apache.org/jira/browse/OAK-6519
Project: Jackrabbit Oak
Issue Type: Task
Components: segment-tar
Reporter: Michael Dürig
Fix For: 1.7.6
This is a follow up to OAK-3349, which introduced tail compactions:
The deduplication caches currently only take the full generations into account
and ignore the tail generations. Cache generations need to be a monotonically
increasing, ordered sequence consisting of the full and tail part of the gc
generation. See
{{FileStoreBuilder.EvictingWriteCacheManager.evictOldGeneration}}. Optimally we
find a way to decouple the segment generation from the cache generations as
these are really separate concerns.
