rdf to nt / nq / flat ttl conversion seems not streamed

[JJ-Author]

the databus client makes no sense if it can not do a file conversion with streamable data in a stream fashion. 32 GB of JVM heap should be enough to convert a ttl file up to terabyte(s) of uncompressed size to ntriples / nquad or turtle_flat . there is the jena streaming api, please take care to make proper use of it https://jena.apache.org/documentation/io/streaming-io.html when the configuration of the format allows streaming.
