Robert Metzger updated FLINK-11148: ----------------------------------- Component/s: Runtime / Coordination > Rescaling operator regression in Flink 1.7 > ------------------------------------------ > > Key: FLINK-11148 > URL: https://issues.apache.org/jira/browse/FLINK-11148 > Project: Flink > Issue Type: Bug > Components: Runtime / Coordination > Affects Versions: 1.7.0 > Reporter: Truong Duc Kien > Assignee: vinoyang > Priority: Major > > We have a job using 20 TaskManager with 3 slot each. > Using Flink 1.4, when we rescale a data stream from 60 to 20, each > TaskManager will only have one downstream slot, that receives the data from 3 > upstream slots in the same TaskManager. > Using Flink 1.7, this behaviour no longer hold true, multiple downstream > slots are being assigned to the same TaskManager. This change is causing > imbalance in our TaskManager load. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
