>
> ConsumeKafka processors can alert to rebalance issues when backpressure is
> engaged on the output connection and is then freed up. This is because we're
> not doing anything with those consumers for a period of time and the kafka
> client detects this and initiates a rebalance. We should ensure that even
> when we cannot send more data due to back pressure that we at least have some
> sort of keep alive behavior with the kafka client. Or, if that isn't an
> option we should at least document the situation.
