Good morning all, In-depth: meaning far more than the manuals from W3C detailed about SPARQL and in specific how bgp and groups get combined as well as how Jena/ARQ internally handle query execution. I understand that "ultimately" in-depth means going to the code but something short of doing that?
I want to focus on memory demands and intermediate caching in memory of partial results, if any. We are having OutOfMemory issues with some types of queries, not all of them and I am trying to troubleshoot it instead of "just throwing" more H/W at it, i.e. memory. BTW, we are using Oracle at the back end ... Any Oracle query hints that you may have found helpful and can share would be greatly appreciated ... Please do not hesitate to contact me if you need additional information. Thank you. Regards, Nikolaos Abatzis New River Systems Corporation 1890 Preston White Drive, Suite 240 Reston, VA 20191
