Not when parallelism is inconsistent (which could mean that we have 2 kafka sources with different number of partitions - I guess this change would not effect them). Could this be a badly configured job, if not it would be useful to detail when this can occur. Are there other topologies that this effects? -- This is an automated message from the Apache Git Service.
