Tomek Rękawek updated OAK-4655: ------------------------------- Fix Version/s: 1.5.11 > Enable configuring multiple segment nodestore instances in same setup > --------------------------------------------------------------------- > > Key: OAK-4655 > URL: https://issues.apache.org/jira/browse/OAK-4655 > Project: Jackrabbit Oak > Issue Type: New Feature > Components: segment-tar, segmentmk > Reporter: Chetan Mehrotra > Assignee: Tomek Rękawek > Fix For: 1.6, 1.5.11 > > Attachments: OAK-4655.v1.patch, OAK-4655.v2.patch > > > With OAK-4369 and OAK-4490 its now possible to configure a new > SegmentNodeStore to act as secondry nodestore (OAK-4180). Recently for few > other features we see a requirement to configure a SegmentNodeStore just for > storage purpose. For e.g. > # OAK-4180 - Enables use of SegmentNodeStore as a secondary store to > compliment DocumentNodeStore > #* Always uses BlobStore from primary DocumentNodeStore > #* Compaction to be enabled > # OAK-4654 - Enable use of SegmentNodeStore for private mount in a > multiplexing nodestore setup > #* Might use its own blob store > #* Compaction might be disabled as it would be read only > # OAK-4581 - Proposes to make use of SegmentNodeStore for storing event queue > offline > In all these setups we need to configure a SegmentNodeStore which has > following aspect > # NodeStore instance is not directly exposed but exposed via > {{NodeStoreProvider}} interface with {{role}} service property specifying the > intended usage > # NodeStore here is not fully functional i.e. it would not be configured with > std observers, would not be used by ContentRepository etc > # It needs to be ensured that any JMX MBean registered accounts for "role" so > that there is no collision > With existing SegmentNodeStoreService we can only configure 1 nodestore. To > support above cases we need a OSGi config factory based implementation which > enables creation of multiple SegmentNodeStore instances (each with different > directory and different settings) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
