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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
