No permanent caching The entire SERVICE result is cached temporarily into memory before further query processing. This is primarily done in case there is a circular/chained SERVICE clause as that can cause nasty things to happen (e.g. you can DOS Fuseki or the remote service by sending particularly crafted queries). However the retrieved results are then drained in a streaming fashion and not cached beyond that. Rob > >Can anybody report on the use of SERVICE Federation in practice? > >Thanks > >Juan
