-------------------------------------------------------------
I've analyzed the MBeans registered by the DocumentNodeStoreService and
SegmentNodeStoreService:
h3. SegmentNodeStoreService
h4. CacheStatsMBean:
* Segment Cache
* String Cache
* Template Cache
* String deduplication cache stats
* Template deduplication cache stats
* Node deduplication cache stats
h4. Maintenance MBeans:
* Segment node store revision garbage collection (SegmentRevisionGC)
* Revision garbage collection (RevisionGCMBean)
* FileStore statistics (FileStoreStatsMBean)
* Segment node store checkpoint management (CheckpointMBean, for role=null)
* Segment node store blob garbage collection (BlobGCMBean, for role=null)
* Segment node store backup/restore (FileStoreBackupRestoreMBean)
* SegmentNodeStore statistics (SegmentNodeStoreStatsMBean)
h3. DocumentNodeStoreService registers:
h4. CacheStatsMBean:
* Document-NodeState
* Document-NodeChildren
* many diff cache stats
* many DocumentStore cache stats
* BlobStore-MemCache
* PersistentCache.NodeCache.* (PersistentCacheStatsMBean)
h4. Maintenance MBeans:
* Document node store checkpoint management (CheckpointMBean)
* Document node store management (DocumentNodeStoreMBean)
* DocumentStore Statistics (DocumentStoreStatsMBean)
* Document node store blob garbage collection (BlobGCMBean)
* Document node store revision garbage collection (RevisionGCMBean)
* Document node store revision garbage collection statistics
(RevisionGCStatsMBean)
* BundlingConfigObserver (BackgroundObserverMBean)
h3. Summary
The "common" set of the registered MBeans between implementations is as
follows: CacheStatsMBean, RevisionGCMBean, BlobGCMBean, CheckpointMBean.
*CacheStatsMBean*
Composite node store doesn't have any cache, so there's no need to create stats.
*RevisionGCMBean, BlobGCMBean*
Composite node store doesn't write any data/blobs on its own, so these MBeans
shouldn't be required as well.
*CheckpointMBean*
It's available for the Composite Node Store as well: CompositeCheckpointMBean.
Other than that, each implementation provides a specific management
(DocumentNodeStoreMBean) and stats (DocumentStoreStatsMBean,
FileStoreStatsMBean) MBeans.

> Review MBean interactions in a composite setup
> ----------------------------------------------

> Key: OAK-6582
> URL: https://issues.apache.org/jira/browse/OAK-6582
> Project: Jackrabbit Oak
> Issue Type: Task
> Components: composite
> Reporter: Robert Munteanu
> Assignee: Tomek Rękawek
> Fix For: 1.8, 1.7.8
>
>
> We should validate how the MBeans currently behave in a composite setup,
> whether any unwelcome interactions arise due to that, and also see if we need
> to add/change MBeans.
