Subject Question about flink message processing guarantee
Date Tue, 01 Dec 2015 22:04:11 GMT
Hello,

I have a question regarding link streaming.  I now if you enable
checkpointing you can have exactly once processing guarantee. If I do
not enable checkpointing what are the semantics of the processing? At
least once?

Best,

Jerry
