Hi TDBsters,
I was just getting back to playing around with tdbstats to optimize some
query responses [1]. At first I couldn't get any counts, but then
discovered that "tdbstats only looks in the default graph (currently)"
[2]. So, I went on to pass one of the graph IRIs, lo and behold, I got
some stats for that graph.
What I'm wondering is, how can I create stats for all of the graphs in
the store and possibly have them represented in stats.opt? Creating
stats for each graph and then merging them (with proper counts) into a
single stats.opt seems cumbersome and possibly incorrect. After all, I
want to be able to query the store in a way that the generated
statistics reflects the store in the most accurate way possible.
Also.. what is the location of rule file where we write the Statistics
Rule Language? I can't see how that supposed to go into stats.opt
because then how would we obtain the counts for the triple patterns?
Thanks!
