Richard Yu commented on KAFKA-3539: ----------------------------------- [~radai] I don't know if this problem is resolved or not. Issue 6705 was closed because it was thought any changes made would be too complex to fix this behavioral issue. > KafkaProducer.send() may block even though it returns the Future > ---------------------------------------------------------------- > > Key: KAFKA-3539 > URL: https://issues.apache.org/jira/browse/KAFKA-3539 > Project: Kafka > Issue Type: Bug > Components: producer > Reporter: Oleg Zhurakousky > Priority: Critical > Labels: needs-discussion, needs-kip > > You can get more details from the us...@kafka.apache.org by searching on the > thread with the subject "KafkaProducer block on send". > The bottom line is that method that returns Future must never block, since it > essentially violates the Future contract as it was specifically designed to > return immediately passing control back to the user to check for completion, > cancel etc. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
