Hi Chris, ... That does sound reasonable. It sounds like it would be worth an initial experiment with Postgresql since the fetch size is the easiest to...
Hi, I use Jena2.1. but i don't understand "...the remove is actually implemented as a rebind step". If I remove directly on the InferedModel, nothing happen. ...
... In the initial Jena2 release "remove" was imlemented as an incremental operation. There was a hard to fix bug in there which was patched around by changing...
