Compress messages before sending to Kafkav3.16+
Compress producer batches before sending them to Confluent Cloud. This example uses lz4 compression.
See config.compression_type for all supported codecs.
Prerequisites
-
A Confluent Cloud cluster
Environment variables
-
KAFKA_TOPIC: The name of your Kafka topic. -
CONFLUENT_CLUSTER_API_KEY: Your Confluent cluster API key. -
CONFLUENT_CLUSTER_API_SECRET: Your Confluent cluster API key.
Add this section to your kong.yaml configuration file:
