If so, wouldn't that solve the back pressure problem at least partially? > Prevent upstream operators from getting too far ahead when downstream > operators are slow > ---------------------------------------------------------------------------------------- > > Key: APEXCORE-570 > URL: https://issues.apache.org/jira/browse/APEXCORE-570 > Project: Apache Apex Core > Issue Type: Improvement > Reporter: Pramod Immaneni > Assignee: Pramod Immaneni > > If the downstream operators are slower than upstream operators then the > upstream operators will get ahead and the gap can continue to increase. > Provide an option to slow down or temporarily pause the upstream operators > when they get too far ahead. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
