i should do some comparison of a fuseki store based application with
others with rel db or proprietary dbs. i use fuseki and tdb stored on an
ssd or a hard disk.
can i simplify measurements with putting pieces of the dataset in
different graphs and then add more or less of these graphs to take a
measure? say i have 5 named graphs, each with 10 million triples, do
queries over 2, 3, 4 and 5 graphs give the same (or very similar)
results than when i would load 20, 30, 40 and 50 million triples in a
single named graph?
is performance different for a named or the default graph?
are there some rules which queries are linear in the amount of data in
the graph? is it correct to assume that searching for a triples based on
a single condition (?p a X) is logarithmic in the size of the data
collection?
is there a document which gives some insight into the expected
performance of queries?
thank you for any information!

Hi all,
We have a project, which we’re trying to productize and we’re facing
certain operational issues with big size files. Especially with copying and
maintaining them on the productive cloud hardware (application nodes).
Did anybody have similar issues? How did you resolve them?
I will appreciate if someone shares their experience/problems/solutions.
Regards,
Stefan
