Can I get some recommendations on how to best tweak/setup memory for my fuseki
servers? Here is my setup:
- I’ve got a single TDB with at least several million triples (I don’t know the
exact amount yet, but perhaps around 10s of millions, maybe 100s of millions…a
the very least, I need it to scale to 100s of millions).
- Everything is put in the default graph currently (wanting to change this…but
can’t the this point in time).
- The “TransitiveReasoner” is being used on the dataset.
What properties are transitive?
(and maybe https://jena.apache.org/documentation/rdfs/?)
- Full text indexing over two different fields is enabled using Lucene.
- The servers are running embedded Fuseki via rdf-delta and sync via a central
rdf-delta server.
- The simplest of queries won’t finish and runs out of memory with, at the very
least, 6 GB of RAM.
Example query?
And is the request causing the database to be sync'ed before the request
starts?
Also, should I be tweaking my non-heap memory to be larger for the Fuseki
server?
Unlikely.

Thanks.
