Manage your Managed Kafka cluster

What you’ll need

To be a company admin. Changes to the cluster, its topics, and its login need one.
A cluster that’s active. Open it from the Kafka page in the Artie Dashboard.

Topics

Create topics from the Topics tab. For everything else, open the topic.

Task	Click	Good to know
Create a topic	New topic	Names use letters, digits, `.`, `_`, and `-`, up to 249 characters. Partitions default to 1. Every partition has 3 replicas.
Add partitions	Add partitions	You can’t remove partitions later.
Change retention	Change retention	Whole days. Topics with tiered storage, even paused, keep at most 14 days.
Tiered storage	Turn on, Pause, Resume, or Change days on disk	Pausing deletes nothing. Compacted topics can’t use tiered storage.
Delete a topic	Delete topic, then type the topic’s name	Deletes the topic and all of its messages for good.

Shorter retention and deleted topics can’t be undone. Kafka deletes the messages, and clients still reading them lose them or get errors.

Topics starting with __ are Kafka’s internal topics and can’t be changed or deleted.

Cluster settings

Change these on the Settings tab. The cluster runs one change at a time.

Setting	Restarts brokers	Good to know
Allowed IP ranges	No	Click Edit, change the ranges, then Save ranges. Takes about a minute. Clients in a range you remove are cut off.
Brokers	No	Add up to 30. Each broker adds a port, so widen your firewall rules first. New topics use every broker; existing partitions stay where they are. Removing brokers isn’t available yet.
Instance type	Yes, one at a time	Brokers restart onto new machines.
Storage per broker	No	Grow only. AWS allows 3 storage changes per 24 hours, at least an hour apart.
Tiered storage	Days on disk and disk cap: yes, one at a time	Turning it on or off doesn’t restart. Turning it off pauses it on every topic.
Storage autoscaling	No	Changes take effect within 12 hours.

If you remove every allowed IP range, any client with the password can connect from anywhere.

To rename the cluster, click its name at the top of its page. The address doesn’t change.

Generate a new password

On the Connect tab, click Generate new password. Your apps stop connecting with the old password as soon as the new one is ready, so update them right away.

Delete and restore a cluster

Delete the cluster

At the top of the cluster’s page, click Delete cluster and type the cluster’s name to confirm. You can delete a cluster when it’s active or failed.

Clients lose access as soon as you delete the cluster.

Restore it within 7 days, if you need to

Artie keeps a deleted cluster’s data for 7 days. Deleted clusters are listed under Deleted on the Kafka page with the date their data is kept until. Click Restore, then Restore cluster.The restored cluster has the same name, address, topics, consumer group offsets, password, size, and IP allowlist. Restoring counts toward your account limits, so a cluster you created after deleting this one can block the restore. A cluster that never finished its first deploy has nothing to restore.

After 7 days, the cluster’s topics and messages are deleted for good.
