JENA-905 : NodeTableCache can optimize a fast-path on entry present.
> Common caching approach
> -----------------------
>
> Key: JENA-905
> URL: https://issues.apache.org/jira/browse/JENA-905
> Project: Apache Jena
> Issue Type: Improvement
> Affects Versions: Jena 2.13.0
> Reporter: Andy Seaborne
> Assignee: Andy Seaborne
> Fix For: Jena 2.13.1
>
>
> Jena can consolidate around one caching implementation for several of these
> areas.
> Some uses of long term caches:
> * TDB (see JENA-801)
> * Rules (see JENA-901)
> * ARQ
> * DatasetGraphCaching, DatasetImpl
> * org.apache.jena.riot.system.IRIResolver
> * Fuseki - SPARQL Query Caching (JENA-626)
> * Core - {{EnhGraph}}.
> One candidate is [Google Guava|https://github.com/google/guava]. It has the
> advantage of providing an atomic get-load operation that would be beneficial
> in some cases.
> However, many systems use different versions Guava. To stop Jena's choice of
> version clashing, we can shade a version to isolate it.
