Thanks Andy,

Cool - my first attempt at write speed testing suggested it was about
the same as N-triples.
Write performance testing is harder (!!!) because you need a big enough
source of data to run without the source itself affecting the numbers.
N-Triples writing has always been faster than reading -

Thrift is 3 layers: a service model, an encoding layer and a handling of
the bytes in/out. RDF Thrift is not using the service layer; I'm using
it elsewhere (Lizard) and it is just fine - it's simpler than netty for
a tightly bound system.
Java Thrift only has dependencies
To easily use the new format, use riot with the --out argument
e.g. convert n-triples to RDF Thrift:
riot --out=TRDF data.nt data.trdf

Sounds proper enough :) with a binary format obviously one has to be very
careful about any changes, but I was more thinking of versioning of the API
of Apache Thrift that your module would use through dependencies.
If I was to use Jena 1.14.0 depending on Apache Thrift say 0.6.0, but
instead

I assume the intent it to add this into Apache Jena as a new module?

It wasn't my plan because it's quite small but I'm open to suggestions.
Pros and cons?

Very cool Andy. How's the write performance?
Good question - not completely sure yet - I'm not expecting a huge gain.
It's easier to test read performance and read performance was what I was
more interested in initially.
For read, you can parse and
Smile is the binary format for Json that comes in Jackson. Since the
transformation from RDF to Json is pretty simple, it occurred to me to
wonder how well that stack would, well, stack up.

to Jena Nodes/Triples.
RDF Thrift takes the string directly off the wire and builds Jena RDF
objects. The encoding puts the RDF terms directly onto the wire with
little overhead.
A nice feature of RDF Thrift files for graphs and datasets is that they
can be concatented like N-triples files. JSON

This is now ready to go if everyone is OK with that.
I'm flagging this up for passive consensus because it adds a new
dependency (for Apache Thrift).
And of course any questions or
