This is needed for users like BGP, which contain a large number of duplicate data (for example in attributes, AS PATH, etc).</p> <p>Create a configurable DataStore/DataBroker decorator, which for specified (wildcard) InstanceIdentifier will maintain a Guava Cache and will transparently replace subtrees with shared versions.</p> <p>Also devise a way how the BGP code can specify that an instance of this decorator should be placed between its BA DataBroker and the backing BI DataStore instance.</p> <p>Operating System: All<br/> Platform: All</p> MDSAL-36

In-memory data store: NormalizedNode caching

Improvement Resolved Done Unassigned Robert Varga Mon, 30 Jun 2014 09:59:39 +0000 Sat, 4 Aug 2018 01:33:15 +0000 Sat, 4 Aug 2018 01:33:15 +0000 0 3 <p>This needs to be model-driven rather than API-driven.</p> <p>The way this should work is that we should have a YANG language extension, which will mark subtrees as candidates for caching. Datastore implementations then can choose to perform interning when it makes sense for that implementation.</p> <p>This has been done via a caching Binding/DOM codec, which is in use by BGP for a long time now.</p> Development External issue ID 1260 External issue URL Issue Type Priority Rank 0|i02vx3:
