Cloud release notes

May 2023

What's New

  • New Setup Guide. A new setup guide has been added to the Dashboard page and contains everything that you need to get up and running with a hosted cluster. On the Dashboard page, you will see step-by-step instructions on adding a payment method, creating and configuring Pulsar clusters, creating topics, setting up clients, and sending messages. The setup guide can be viewed by logging in to the StreamNative Cloud Console and clicking Dashboard on the left navigation pane. new setup guide

  • Organization Usage Page. Customers with StreamNative Managed Clusters (Hosted + BYOC) can now view both real-time and historical cluster usage data on the new Organization Usage page. This page features charts visualizing the usage dimensions (Compute Units, Storage Units, Throughput, and Storage Size) for all clusters within an organization. You can view usage by instance or in aggregate across your organization and narrow the date range to hone in on usage over a specific time period. You can view up to the past 60 days of usage. org usage view

  • Improved Usability for Kafka Clients. Customers with clusters that have Kafka protocol enabled will include a new Kafka Clients page that walks you through using Kafka clients to connect to your clusters. The Kafka client setup wizard enables application developers using Kafka clients to easily connect to their organization's Pulsar cluster. This page includes client libraries (Java, Go, Python, and Node.js), Apache Kafka CLI tools, KStream applications, and KSQL. In addition, Kafka protocol is also enabled by default on all new managed Pulsar clusters (Hosted + BYOC). kafka client setup wizard

Other Enhancements

  • Refreshed Dashboard for managing instances and user accounts on StreamNative Cloud Console. You will see two new cards on the Dashboard page, surfacing additional information about your organization's instances and user accounts, allowing you to manage instances and user accounts directly from the Dashboard page without going to a separate screen.

  • New hosted clusters on Pulsar 2.10.3.7. New hosted Pulsar clusters (clusters hosted on StreamNative's public cloud account) will now be on version 2.10.3.7, where they were previously on version 2.9.3.21. As a result, you will benefit from the following enhancements:

    • Pulsar provides automatic failure recovery between the primary and backup clusters.
    • With the lazy-loading feature added to PartitionedProducer, fewer producers are needed and the broker memory utilization is improved.
    • Topic map support added with a new TableView type using key values in received messages.

    To learn more about features offered in this version, see What's New in Apache Pulsar 2.10. If you would like to upgrade your cluster, please submit a ticket.

  • Audit log now includes produce and consume events. For clusters on Pulsar 2.10.3.7 and later, Produce and Consume events can now be tracked in the audit log. audit log

  • Streamlined instance deletion experience. You can now delete an instance and all Pulsar clusters within it in one step, rather than having to individually delete all associated clusters before deleting the instance. streamlined instance deletion

  • Snowflake Sink Connector upgrade. The Snowflake Sink Connector on StreamNative Cloud Console has been upgraded from 2.9.4.1 to 2.10.3.4. In addition to smaller bug fixes, this connector now supports concurrency where it previously did not, meaning the replicas can now be set to more than 1 when configuring a connector. Snowflake Sink Connector supports concurrency

Bug Fixes

  • Fixed an issue preventing the creation of a Debezium-Postgres connector via the StreamNative Cloud Console.
  • Fixed an issue where namespaces with lots of topics would sometimes show a spurious error on the Namespace page of the StreamNative Cloud Console.
  • Fixed an issue causing configuration details on the Functions page to display without formatting.

March + April 2023

What's New

  • New Clients Page. The Clients page makes it easier to connect to a Pulsar cluster with your client of choice. You'll find comprehensive example snippets with better syntax highlighting, more programming languages (Java, Go, Python, C++, Node.js, Rust, Spring, C#), and more REST API and CLI tool examples.

    You can download authentication tokens (either an OAuth2 credential file or a JWT token) directly from the Clients page.

    To view the new page, select a programming language, CLI tool, or REST API. Then, you can see installation and connection instructions. Watch the video below for an example of connecting to a cluster using the Java client. Client Setup page in the Cloud Console

  • Pulsar Transactions on StreamNative Cloud. You can now configure Pulsar Transactions using the StreamNative Cloud Console.

    Pulsar Transactions (in Beta on StreamNative Cloud) enable event-streaming applications to consume, process, and produce messages in one atomic operation, including:

    • Atomic writes across multiple topic partitions
    • 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

Improvements

  • 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.
