The consumer will simply leave the newly > created partitions out and thus miss all data which is written to the new > partitions. The reason seems to be a static assignment of partitions to > consumer tasks when the job is started. > We should either fix this behaviour or clearly document it in the online and > code docs. -- This message was sent by Atlassian Jira (v8.3.4#803005)
