My comment was just about calling out a possible need for more shutdown
orchestration.
I am not reviewing.
> KafkaWriter is asynchronous and may lose data on node failure

> Currently, we do not block for data to be sent from kafka writer and we do
> not batch. Unfortunately, the send call is asynchronous, so if the node dies
> before the data is actually sent from kafka then it will drop data. It is
> highly unlikely that we will be able to make kafkawriter synchronous in a
> performant way, so we will likely need to batch in the parser and enrichment
> topologies.
