------------------------------
Summary: Fuseki upload should avoid having to cache the data into
memory where possible
Key: JENA-602
URL: https://issues.apache.org/jira/browse/JENA-602
Project: Apache Jena
Issue Type: Improvement
Components: Fuseki
Affects Versions: Fuseki 1.0.0
Reporter: Rob Vesse
Currently when uploading data files to Fuseki it always caches the data
in-memory even if the underlying dataset is transactional. The reason stated
in code is that since a form multipart request is used there is no way of
knowing which graph the data is destined for because you may see the graph name
after the data.
With the ongoing Fuseki UI refactor it may be worth rethinking this, what we
could do is require that any graph name is a query string parameter thus
guaranteeing up front access to it and that only the data is POSTed in the form
multipart request.
If this change was made we could then support transactional uploads since you'd
always know the graph to write to in advance and this would make file uploads
significantly faster for systems like TDB.
