Stephan Ewen commented on FLINK-939:
------------------------------------
Great news!
I'll try and have a look at it this weekend. I'll also try to sync with
Asterios with respect to replacing the RPC.
The blob service is important for that, because the new RPC will have a limited
maximum frame size. We need to delegate large payloads to the blob service,
> Distribute required JAR files with seperate service

> Currently, required user JAR files are distributed via the RPC service in
> {{JobGraph.writeRequiredJarFiles(DataOutput, AbstractJobVertex[])}}. The RPC
> service then tries to allocate a buffer on the client side heap to write the
> on-disk JAR, which [can lead to
> problems|https://github.com/apache/incubator-flink/pull/18].
> This should be replaced with a seperate service.
