Basically I have 2 issues right now: 1) Running my assembly clustered This seems to be the easy one, since I am using Apache Karaf for building my assembly/distribution. Karaf has a subproject called Cellar for clustering. Here just have to dive in a get it done. 2) Having a cluster aware datastore (Jena TDB) Googling around leaves me clueless. Sometimes it appears TDB can be used in clustered environments others it appear it can't. I sure couldn't find any recipe how to get it done. I should probably ask this on the Jena mailing list, but I am trying this one first since you guys seem to have quite some experience with TDB. I am wondering if I can really use TDB in a clustered setup or if need to switch to another datastore to accomplish this. Probably SDB can be used for this but I fear a performance penalty. Any thoughts? Regards, Minto
