Jay Kreps resolved KAFKA-910. ----------------------------- Resolution: Duplicate > Randomize the backoff in the clients to avoid all clients from sending > metadata requests at the same time > --------------------------------------------------------------------------------------------------------- > > Key: KAFKA-910 > URL: https://issues.apache.org/jira/browse/KAFKA-910 > Project: Kafka > Issue Type: Bug > Components: replication > Affects Versions: 0.8.0 > Reporter: Neha Narkhede > Assignee: Neha Narkhede > Priority: Critical > Labels: kafka-0.8, p1 > > Currently, all producer and consumer clients use a static backoff. So if a > broker fails, most topics will lose some leaders. All clients will notice the > absence of a leader at the same time, backoff the same time and send metadata > requests. Instead, clients should randomize the backoff to avoid a herd effect -- This message was sent by Atlassian JIRA (v6.2#6252)
