[jira] [Created] (FLINK-5169) Make consumption of input channels fair

Ufuk Celebi created FLINK-5169:
----------------------------------

             Summary: Make consumption of input channels fair
                 Key: FLINK-5169
                 URL: https://issues.apache.org/jira/browse/FLINK-5169
             Project: Flink
          Issue Type: Improvement
          Components: Network
            Reporter: Ufuk Celebi
            Assignee: Ufuk Celebi
            Priority: Critical
             Fix For: 1.2.0, 1.1.4


The input channels on the receiver side of the network stack queue incoming data and notify the input gate about available data. These notifications currently determine the order in which input channels are consumed, which can lead to unfair consumption patterns where faster channels are favored over slower ones.
