Subject Re: Limit buffer size for a job
Date Mon, 11 Apr 2016 16:19:28 GMT
Hi!

Ufuk's suggestion explains how to buffer less between Flink operators.

Is that what you were looking for, or are you looking for a way to fetch
more fine grained in the source from the message queue?
What type of source are you using?

Greetings,
Stephan
