Abstract
Disclose is an improved approach for caching lexical values for RDF data. A compact, efficient resource ID to value mapping is stored in memory, where the cache is stored in memory such that the overhead of accessing and updating it is minimized. The advantage of this approach is improved query performance, since the database is performing less work with the in-memory RDF resource caching. In addition, throughput and performance of the database are also improved.
