Disable AAF Authentication for DMaaP MR

Authentication via AAF is the default setting in Dublin DMaaP MR.  But sometimes it is useful to disable this check and the dependency on AAF  (e.g. for a demo setup).  This section provides some instructions for disabling AAF for the various DMaaP components.

Change Kafka Log Retention

"Kafka Log" refers to the queue used to store messages for each topic.  "Retention" is the max time an individual message should remain in the queue (regardless of whether it was read by a consumer or not)  The default log retention time (i.e. how long a message will be retained)  is 7 days.  A topic with lots of volume might consume the amount of disk space allotted to all the kafka message queues, so in some deployment environments the retention time should be modified.

In your  local deployment, if you know the log retention needs of all Kafka topics, update the default log retention by setting the following environment variable in Kafka statefulset.yaml.

Retention based on time:

KAFKA_LOG_RETENTION_HOURS ( you can also set the retention in minutes and ms using the environment variables KAFKA_LOG_RETENTION_MINUTES and KAFKA_LOG_RETENTION_MS)

Retention based on topic partition size:

KAFKA_LOG_RETENTION_BYTES

Following are the some of the useful commands to override/view/delete( the override)  the topic retention at topic level at run time

To update topic level log retention based on time:

/opt/kafka/bin/kafka-configs.sh --zookeeper message-router-zookeeper:218 --entity-type topics --entity-name <<topic--name>> --alter --add-config retention.ms=<<>>

To update topic level log retention based on topic partition size:

/opt/kafka/bin/kafka-configs.sh --zookeeper message-router-zookeeper:2181 --entity-type topics --entity-name <<topic--name>> --alter --add-config retention.bytes=<<>>

View the topic level overrides:

bin/kafka-configs.sh --zookeeper message-router-zookeeper:2181 --entity-type topics --entity-name <<topic--name>> --describe

Remove the topic level overrides:

/opt/kafka/bin/kafka-configs.sh --zookeeper message-router-zookeeper:2181  --entity-type topics --entity-name <<topic--name>> --alter --<<overrided property to remove>>
