Hi Folks. I know that Fuseki is a server that sits on top of TDB and provides SPARQL capabilities over HTTP , if I were to write code in Java using the Apache Jena API do I need the Fuseki server to be running and have the data transmission via HTTP to execute a read query? is there other faster mechanism like JDBC where I can connect directly to the TDB without going thru Fuseki for querying it ? Thank You |

You can use TDB directly (same JVM). See http://jena.apache.org/documentation/tdb/tdb_transactions.html Otherwise Fuseki(+it's internal TDB) over HTTP is acting like a SQL database server over JDBC. Andy thanks for the clarification , I think choice is between performance single JVM vs sclability Fuseki via HTTP. The nature of the query load will matter - normally only if it is large numbers of small queries will the overhead of communicating with Fuseki show up. |
