Errai + streaming data to clients

mnenchev Apr 27, 2010 4:27 AM

Hi, does errai supports data streaming? For example market data (3-4 messages per second)? I.e. data strings that must be sent very often to all clients that are subscribed to the market. Could you compare Lightstreamer with errai bus, please? (http://www.lightstreamer.com/) Regards.

Yes, we've been testing the bus with up to several hundreds of messages per second and client.
Take a look at the tore example. It contains a very rudimentary stock quote demo.

Thanks for the quick response. I downloaded the last snapshot from:
http://hudson.jboss.org/hudson/job/Errai/lastStableBuild/org.jboss.errai$errai-distribution/artifact/org.jboss.errai/errai-distribution/1.1-SNAPSHOT/errai-1.1-SNAPSHOT.zip

And i tried to run the examplse with mvn gwt:run, but i got exceptions for each one.
Caused by: org.apache.maven.artifact.resolver.ArtifactNotFoundException: Unable to download the artifact from any repository

org.jboss.errai:errai-bus-demos:pom:1.1-SNAPSHOT

Where can i find this "tore example"?

Regards.
