JENA-626 SPARQL Query Caching
The implementation of SPARQL Query Caching. The initial idea was to create
a separate service endpoint that invokes SPARQL_Query. The challenge we faced
was to intercept the results data when it is directly written into
ServletOutputStream. Currently the results data is copied into cacheBuilder
object before it is written to ServletOutputStream. The implementation caches
the results for 5 mins and then it invalidates the cache.
We have seen good performance benefit with initial test data.
