Enable and disable tiered storage on an existing Amazon MSK topic
These sections cover how to enable and disable tiered storage on a topic that you've already created. To create a new cluster and topic with tiered storage enabled, see Creating a cluster with tiered storage using the AWS Management Console.
Enabling tiered storage on an existing Amazon MSK topic
To enable tiered storage on an existing topic, use the alter
command syntax in the following example. When you enable tiered storage on an
already existing topic, you aren't restricted to a certain Apache Kafka client
version.
bin/kafka-configs.sh --bootstrap-server $bsrv --alter --entity-type topics --entity-name msk-ts-topic --add-config 'remote.storage.enable=true, local.retention.ms=604800000, retention.ms=15550000000'
Disable tiered storage on an existing Amazon MSK topic
To disable tiered storage on an existing topic, use the alter
command syntax in the same order as when you enable tiered storage.
bin/kafka-configs.sh --bootstrap-server $bs --alter --entity-type topics --entity-name MSKTutorialTopic --add-config 'remote.log.msk.disable.policy=Delete, remote.storage.enable=false'
Note
When you disable tiered storage, you completely delete the topic data in
tiered storage. Apache Kafka retains primary storage data , but it still
applies the primary retention rules based on
local.retention.ms. After you disable tiered storage on a
topic, you can't re-enable it. If you want to disable tiered storage on an
existing topic, you aren't restricted to a certain Apache Kafka client
version.
