Two question about flink

[hustjackie <hu...@gmail.com>]

hi all：

I am a beginner of Flink, may I ask two question:

1. in cluster mode, if one node has crash, what's the failover? is there one mechanism to guarantees fault-tolerance?
2. is there a performance report?




Thanks
Longda

We currently support coarse-grained fault tolerance via program restarts.
This will be soon extended to more fine grained fault tolerance, where only
necessary parts of a program are re-executed.

There are some new performance numbers coming up soon. I think there are
also some older numbers from Robert. Let's wait what he has to say.
