 | `splunk.hec.raw.line.breaker` | Only applicable to /raw HEC endpoint. The setting is used to specify a custom line breaker to help Splunk separate the events correctly.</br> **NOTE:** <br/> For example, you can specify `"#####"` as a special line breaker. Internally, the Splunk Kafka Connector will append this line breaker to every Kafka record to form a clear event boundary. The connector performs data injection in batch mode. On the Splunk platform side, you can configure **`props.conf`** to set up line breaker for the sourcetypes. Then the Splunk software will correctly break events for data flowing through /raw HEC endpoint. For questions on how and when to specify line breaker, go to the FAQ section.|`""`|
