Kafka destination plugin

Apache Kafka is a distributed streaming platform used for building real-time data pipelines and streaming applications. It provides a high-throughput, low-latency platform for processing and transmitting large amounts of data, including logs, metrics, events, and other types of telemetry data.

This plugin provides a flexible and configurable way to transmit your data to Kafka. Whether you're working with logs, metrics, traces, or other types of telemetry data, the Kafka destination plugin in Calyptia Core provides a reliable and efficient way to integrate your data with Kafka for real-time processing and analysis.

The queue_full_retries option set the number of local retries to enqueue the data. The default value is 10 times, the interval between each retry is 1 second. Setting the queue_full_retries value to 0 sets an unlimited number of retries.

Message Key Field

If set, the value of Message_Key_Field in the record will indicate the message key. If not set nor found in the record, Message_Key will be used (if set).
