What's New

  • Documentation Site Refresh

    StreamNative’s documentation site has been redesigned. There are now two separate sub-sites for StreamNative Managed Cloud and StreamNative Platform, and each section is organized by the type of work that you are trying to do:

    • Build Applications: This section is for Pulsar users within companies that are using Pulsar to build applications, such as application development teams. (They do not need to know anything about managing or architecting/administering Pulsar.)
    • Administer: This section is for Pulsar power users and core platform teams that manage Pulsar components. This section includes information on creating tenants, namespaces, and topics, as well as managing organizations and instances.
    • Manage Infrastructure: This section is primarily for customers who are managing clusters and infrastructure. (That is, SRE folks - cluster, metrics, logs.)


Other Enhancements

  • Show memory and CPU when configuring Brokers and Bookies

    The Advanced tab for configuring a Pulsar cluster now surfaces both memory and CPU for Brokers and Bookies, making it easier to understand your cluster’s compute and storage capabilities.

    Broker and bookie usage

  • Pulsar version for newly deployed Hosted clusters

    Updates from version include the following:

    • Upgrade Pulsar server Java build version to 17.
    • Support chunking with shared subscriptions.
    • Support the pluggable topic factory.
    • Support configuring the compression type for ManagedCursorInfo to balance storage resource usage.

    To learn more about updates included in this version, see What's New in Apache Pulsar 2.11.

    You can see what version your Pulsar cluster is on by checking the Details tab on the cluster configuration page. If you want to upgrade your existing clusters, please submit a ticket.

    • Atomic acknowledgments across multiple topic partitions
    • All the operations made within one transaction either all succeed, or all fail
    • Consumers are ONLY allowed to read committed messages Transactions


  • Navigation bar refresh. The new design for the navigation bar on the StreamNative Cloud Console includes a lighter theme and updated icons, making it easier to navigate the console. To colocate all Admin tasks, the Clients tab was moved to the Admin section. New Cloud navigation bar

  • Pulsar cluster names. With this release, the maximum number of characters for Pulsar cluster names is 10 characters. (Note: Existing Pulsar clusters with names longer than 10 characters are not affected by this change.)

  • Request a region. If you are creating a new cluster using StreamNative Cloud Console and a region is not currently supported, you can request support for that region. Support for requesting a new region

Bug Fixes

  • Previously, it was possible to delete instances with active clusters. Now, before you can delete an instance, you must first delete all clusters within that instance.

  • Previously, you could not disable the audit log once it was turned on (enabled). With this release, it is now possible to toggle the audit log on and off.

Breaking Changes

  • Deprecation of free cloud. New customers can no longer sign up for free clusters. If you are interested in requesting access to StreamNative Cloud, please Contact us.

Improvements for new clusters

We have made several improvements to new Pulsar clusters on StreamNative Cloud. These changes will not impact existing clusters, but new clusters will benefit from the following enhancements:

Cluster configurations added to the cluster Overview tab

You can view a new configuration section on the Overview tab on the Clusters page in the StreamNative Cloud Console for better visibility and accessibility. This allows you to quickly access and manage information on the backlog quota, backlog retention policy, subscription throttling rate, and producer/consumer limits per topic.

Cloud Console optimizations

To facilitate easier debugging and troubleshooting of data issues with a topic, a new Stats tab has been added to the Topic page in StreamNative Cloud. This tab displays the output of the commands topic-stats and topic-stats-internal, making it easier for you to access and analyze topic statistics, streamlining the debugging process.

Instance selection made clearer

The StreamNative Cloud Console dashboard now clearly indicates the currently selected instance through the addition of a checkmark. This enhancement eliminates confusion and allows you to easily identify the active instance.

March 2022

StreamNative Cloud is designed to make it easy for teams to leverage the power of Apache Pulsar. We are working hard on improving the StreamNative Cloud Console to make it simpler for teams to provision and understand their Pulsar clusters.

Today, we are pleased to announce the release of an updated Cloud Console that brings some new features and refinements to better meet your needs. This release features a new Cloud Dashboard and Navigation to provide better visibility into your clusters and to provide more intuitive navigation. This is the first in many releases, and over the coming weeks and months. Expect to see more improvements that add additional features and refinements in the future.

If you have any questions or issues about this update, don't hesitate to reach out through the support portal or give us feedback through the chat app.


  • New Dashboard page that serves as a quick health check of your instances with your most important tasks close at hand.
  • Updated navigation menu to simplify and streamline the management of StreamNative and Pulsar resources.
  • Significant internal re-architecture to make the UI faster and more responsive, without some of the previous delays of API changes not being shown in the UI.

What's New

  • Cloud Console Dashboard and login changes
    • This new home page is designed to make it easy for you to see the status of your instances and to quickly get started with StreamNative Cloud.
    • The Cloud Console now remembers your most recent organization and instance.
  • New Navigation
    • The navigation menu has been significantly changed to make navigation more intuitive.
    • A new quick switcher for tenants and namespaces has been added to the navigation bar.


  • Update your bookmarks! The links have changed. The previous links did not allow for deep linking.
  • Certain metrics, such as number of topics in a namespace, traffic, and others have been removed. These metrics were a point-in-time snapshot that was often out-of-date, potentially leading to confusion.
  • Numerous bug fixes and performance improvements have been implemented. These bug fixes include issues with changes via the Pulsar REST API not being visible within the UI and issues with large numbers of topics or namespaces.

Future plans

This update is just the beginning. More features are coming soon, including:

  • Additional dashboard cards with contextual actions to simplify managing your Pulsar infrastructure.
  • Richer, historical metrics to see how your instance and applications are performing.
  • Additional improvements to the provisioning workflow to make it easier to deploy and manage instances and clusters.
