We’re using Fuseki 3.16.0, and I’d appreciate guidance on getting the most detailed explanation available for query execution plans. Given that Fuseki is built upon and/or incorporates more discrete Jena components, e.g., TDB and ARQ, there appears to pertinent information in several places e.g.,
https://jena.apache.org/documentation/query/explain.html https://jena.apache.org/documentation/query/logging.html https://jena.apache.org/documentation/fuseki2/fuseki-logging.html https://jena.apache.org/documentation/tdb/optimizer.html but I wonder if some of it supersedes others. Further, there are seemingly several related command options such as “tdb2.tdbquery –explain”, “sparql –explain”, and “arq.sparql –explain” (I believe one or more of these may be an alias for another). Assuming we’ve generated a statistics file, what command and accompanying options and configuration parameters would you recommend for introspecting the most detailed information on how Fuseki is executing a query? Thank you. --Jeff
