----------------------------------
And now a non blocking Turtle parer is available here too

> support for Non Blocking Parsers

> Project: Apache Jena
> Issue Type: Improvement
> Reporter: Henry Story
>
> In a Linked Data environment servers have to fetch data off the web. The
> speed at which such data
> is served can be very slow. So one wants to avoid using up one thread for
> each connections (1 thread =
> 0.5 to 1MB approximately). This is why Java NIO was developed and why servers
> such as Netty
> are so popular, why http client libraries such as
> https://github.com/sonatype/async-http-client are more
> and more numerous, and why framewks such as http://akka.io/ which support
> relatively lightweight
> actors (500 bytes per actor) are growing more viisible.
> Unless I am mistaken the only way to parse some content is using methods that
> use an
> InputStream such as this:
> val m = ModelFactory.createDefaultModel()
> m.getReader(lang.jenaLang).read(m, in, base.toString)
> That read call blocks. Would it be possible to have an API which allows
> one to parse a document in chunks as they arrive from the input?
