• Supported Kafka versions: 0.9+

Kafka can be used as an intermediary buffer between collector and an actual storage. jaeger can be configured to both act as the collector for Kafka data before adding it to a Kafka topic and also as a ingester to get data from Kafka and forward it to another storage backend.

Writing to Kafka is particularly useful for building post-processing data pipelines.

Kafka also has the following officially supported resources available from the community:

• Docker container  for getting a single node up quickly
• Helm chart  by Bitnami
• Strimzi Kubernetes Operator
