-----------------------------------------
Summary: Add topology-backed cache diagnostics and compatibility
cleanup
Key: HBASE-30329
URL: https://issues.apache.org/jira/browse/HBASE-30329
Project: HBase
Issue Type: New Feature
Components: BlockCache
Affects Versions: 4.0.0-alpha-1
Reporter: Vladimir Rodionov
Assignee: Vladimir Rodionov
- Review all uses of CombinedBlockCache, getBlockCaches(), and
BlockCacheBackedCacheAccessService.
- Replace test-only casts with CacheAccessServiceTestFactory helpers where
appropriate.
- Ensure topology-backed service exposes existing diagnostic capabilities:
cached block iteration,
fully cached files,
stats,
size counters,
cache names.
- Add focused tests proving old observable behavior still works through
CacheAccessService.
