Max insertion rates for TDB, et. al.

2013-08-27 Thread Claude Warren
Does anyone have a measure of max insertion rate for TDB and/or other storage implementations? I am trying to determine if it is feasible to use Jena in an environment with frequent small (7-19 triples) inserts and infrequent (7x day) reads. This is essentially a system to store some application

PS. both the Fuseki and Seki instances are currently wide open, but I'm pretty sure decent auth won't be too difficult (I'm in the process of adding auth to Seki, hopefully openshift somewhere will allow me to block writes to Fuseki outside of the Seki domain). Worst case, it should be possible to

I think the problem is that in the cases where this does not apply you return the original input rather than making a copy so you overwrite some/all of your changes Try replacing the following: return opUnion; With the following: return super.transform(opUnion, left, right); NB - I haven't

Hi all, I'm having some more problems with Fuseki and full text search. I have an InfModel backed by a TDB dataset, which I've added a Lucene text index to. I'm having problems with updates and select queries resulting in exceptions being thrown by Fuseki. I am running Fuseki 0.2.8-SNAPSHOT

But If I stop the JVM of my Fuseki server (and TDB) from my IDE console, restart it and then query the dataset, the query returns to me null values for some elements of some triples. How do you stop the JVM? Also what is your TDB setup? This sounds like one of two things: 1 - Dataset
