Dear all, I loaded six RDF datasets to Fuseki with sizes comprised between 20 Kb and 20 Mb. To host these six datasets (in persistent mode) Fuseki is using over 1 Gb of RAM and could soon get killed by the system (running on a container platform).
How much RAM are you giving Fuseki? (Why "could soon get killed"?)
This demand on RAM for such small datasets appears excessive. What strategies are there to limit the RAM used by Fuseki?
The persistent store can be controlled with https://jena.apache.org/documentation/tdb/store-parameters.html Specifically: tdb.node2nodeid_cache_size tdb.nodeid2node_cache_size file tdb.cfg in the Do not change the database layout parameters after it is built! Or put them all in one datasets as named graphs. Or load them as plain files (if they are read-only) Andy
Thank you. -- Luís
