Chetan Mehrotra created OAK-4655: ------------------------------------ Summary: Enable configuring multiple segment nodestore in same setup Key: OAK-4655 URL: https://issues.apache.org/jira/browse/OAK-4655 Project: Jackrabbit Oak Issue Type: Improvement Components: segment-tar, segmentmk Reporter: Chetan Mehrotra Fix For: 1.6
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 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)
