Function proxy: template-based proxy caching for table-valued functions
Qiong Luo, Wenwei Xue · 2004
In this paper, we demonstrate advanced proxy-caching techniques for function-embedded queries. We term our proxy a function proxy. It does not only service a function-embedded query that is an exact match to a previous one, but also services a query that can be answered by processing results of previous queries. We focus on table-valued functions (which return a set of tuples) as opposed to scalar functions (which return a scalar value), because the former brings additional challenges as well as opportunities for our function proxy.
