Kafka Connections

Important note: Our Kafka support is in beta version.

This page shows all existing Kafka connections. Via the context menu, you can edit and delete these or create new ones. Lobster_data always acts as a Kafka client and not as a server and currently only uses the Kafka message function (no streaming).

(1) You can use this alias (as name of the connection) in the Input Agent Kafka and Response Route Kafka.

(2) Messages can only be received and sent via active connections.

(3) Usually, several hosts are defined here (separated with commas), since Kafka is usually operated in a cluster.

(4) An optional identifier of a Kafka consumer (in a consumer group) that is passed to a Kafka broker with every request.

(5) Additional connection properties can be defined via the context menu. Note: The property group.id, for example, defines the consumer group and is mandatory for 'subscribe'. Lobster_data creates this property per consumer as grp + <hash code of topic> if it is not explicitly specified.
