This property may also be set per-message by passing callback=callable (or on_delivery=callable ) to the confluent_kafka.Producer.produce() function.

If your Kafka broker is running somewhere else (not at broker.kafka:9092), you will have to provide custom configuration for Kafka broker host while installing fission. You can do that by creating a config file, set the value of kafka.brokers to your How to use Kafka Connect - Getting Started¶.

The buffer size and thread count will depend on both the number of topic partitions to be cleaned and the data rate and key size of the messages in those partitions. As of Kafka version 0.10.2.1, monitoring the log-cleaner log file for ERROR entries is the surest way to detect issues with log cleaner threads.

In the docker-compose.yml, I’ll add the new dlq-topic with replication factor 1 and partition 1.
