Apache Jena is a framework for developing Semantic Web and Linked Data
applications in Java. It provides implementation of W3C standards for
RDF and SPARQL.
The Jena development community is pleased to announce the release of
Apache Jena 3.5.0.
Introducing TDB2:
http://jena.apache.org/documentation/tdb2/
*TDB2 is not compatible with TDB1*
Compared to TDB1:
* No size limits on transactions : bulk uploads into a live Fuseki
can be 100's of millions of triples.
* Models and Graphs can be passed across transactions
* No queue of delayed updates, no transaction backlog problems.
* "Writer pays" - readers don't
All work for update is done on the writer thread.
* Datatypes of numerics preserved; xsd:doubles supported.
TDB2 is subject to change.
We solicit any and all feedback (good and bad!) about TDB2 to help
advance it to deployment-ready.
