Confluent Cloud Release Notes

Note that Confluent Cloud clusters are continuously updated with improvements and new features. This page highlights significant user-facing features and updates to Confluent Cloud.

June 30, 2022

Confluent Terraform Provider v1.0.0 is now generally available.

View the full changelog on Github.

June 28, 2022

Confluent Terraform Provider v0.13.0 is now available in public preview. It contains the following changes:

  • Added support for the kafka_api_key, kafka_api_secret, kafka_rest_endpoint attributes in a provider block to make the rest_endpoint attribute and credentials block optional for confluent_kafka_acl and confluent_kafka_topic resources (#37, #54).
  • Added disable_wait_for_ready attribute to disable readiness check for confluent_api_key resource #25, #51).
  • Added support for pausing / resuming a connector by adding status attribute for confluent_connector resource.

View the full changelog on Github.

June 27, 2022

Confluent Terraform Provider v0.12.0 is now available in public preview. It contains the following changes:

  • Reverted resource versioning changes introduced in 0.11.0. For example, the confluent_environment_v2 resource was renamed to confluent_environment. User feedback on versioned resources made it clear that the pain of manually updating the TF state file outweighs the potential benefits of deprecation flexibility that versioned resources could have provided. In order to avoid forcing users to edit their TF state files (either manually or by running commands like terraform state mv) in the future, TF state migrations will be handled within the Confluent Terraform Provider whenever possible.

Follow Confluent Provider 0.12.0: Upgrade Guide to update your TF state and TF configuration files accordingly. Direct updates from both 0.10.0 and 0.11.0 to 0.12.0 are supported.

  • Renamed the http_endpoint attribute to rest_endpoint for the confluent_kafka_cluster, confluent_kafka_topic, confluent_kafka_acl resources and data sources to match the Cluster settings tab in Confluent Cloud Console, where the corresponding attribute is named the REST endpoint.
  • Renamed the api_key and api_secret attributes of the provider block to cloud_api_key and cloud_api_secret, respectively.

  • Updated confluent_kafka_cluster and confluent_environment data sources to accept display_name as an input.
  • Improved logging to simplify debugging process:
    • Started using the tflog package: now you can enable detailed logs and use grep and a corresponding “logging key” to find all entries related to a particular resource, for example, grep "environment_id=env-9761j7" log.txt.
    • Revised and structured logging messages to output non-sensitive attributes instead of unreadable references.

    • Confluent Cloud networks are now first-class citizens, with independent lifecycle management of private dedicated clusters and networks.
    • Supports self-service provisioning of multiple Dedicated clusters, reducing manual effort and improving network resource utilization. For example, you can reuse /16 CIDR blocks across multiple clusters for VPC peering.
    • Users can select zones for the Confluent Cloud network. A Confluent Cloud network is always multi-zone and all multi-zone clusters in it are added to the same zones.
  • Adds NetworkAdmin RBAC role targeting network lifecycle management, enabling the separation of concerns between infrastructure and application development teams in an organization.

March 24, 2022

Consumer lag is now available as a metric in the Confluent Cloud Metrics API. For more details see Monitor Consumer Lag.

March 22, 2022

Granular role-based access control (RBAC) for Kafka resources is promoted to General Availability. For details, see Use Role-Based Access Control (RBAC) in Confluent Cloud.

Highlights:

  • Adds roles for DeveloperRead (Read access), DeveloperWrite (Write access), DeveloperManage (Create, Delete, Change configurations), ResourceOwner (full access, including granting permissions) for Kafka resources to enable using RBAC for managing access to topics, consumer groups, and transactionalIDs.
  • Adds the Operator role that enables Describe-only access at the Organization, Environment, and Cluster level. For details, see Operator.
  • Restrict user and service accounts using RBAC and ACLs.
  • User and service accounts can be granted multiple roles.
  • Adds the MetricsViewer role that grants access only to metrics for specified user and service accounts. This role cannot access data in Kafka clusters.
  • Granular RBAC for Kafka resources is only available in Standard and Dedicated clusters. This functionality is not available on Basic clusters.
    • Note that administrator roles are enforced on Basic clusters as usual.
  • Stream lineage views can be accessed by administrator and operator roles (OrganizationAdmin, EnvironmentAdmin, CloudClusterAdmin, MetricsViewer, and Operator). Developers cannot access.

Gaps:

  • User and service accounts with DeveloperRead, DeveloperWrite, DeveloperManage, and ResourceOwner roles on resources within a Kafka cluster can see all of the metrics within that cluster. We are actively working to block this access.
  • Any user with access to a resource in a cluster can see all of the consumers and producers of a cluster, regardless of which topic on the cluster the consumer consumes from. Engineering is actively working to block this access.
  • Some users might receive email notifications related to Connector create operations, even if they are not directly related to or involved in these operations. If a user receives a notification email message, they cannot access the connector unless they are assigned the required roles. Engineering is working to resolve this issue.

March 9, 2022

Confluent Cloud Terraform Provider v0.5.0 is now available in public preview. It contains the following changes:

  • Added support for Kafka topic configuration updates (#11).

  • Fixed Provider produced inconsistent result after apply error when creating a lot of Kafka topics (#40).
  • Fixed delete operation for confluentcloud_kafka_topic resource to avoid 400 Bad Request: Topic ‘foobar’ is marked for deletion error when recreating a lot of Kafka topics (#50).
  • Added support for old environment IDs (#43).

View the full changelog on Github.

February 22, 2022

January 28, 2022

Confluent Cloud Terraform Provider v0.4.0 is now available in public preview. It contains the following changes:
  • Added data sources for: confluentcloud_environment, confluentcloud_kafka_cluster, confluentcloud_kafka_topic, and confluentcloud_service_account
  • Improved readability of error messages by adding details to them
  • Resolved potential HTTP 429 errors by adding automatic retries with exponential backoff for HTTP requests
  • Added graceful handling for resources created via Terraform but deleted via Confluent Cloud Console, Confluent CLI, or Confluent Cloud APIs.
  • Fixed minor bugs and docs issues.
Breaking Changes:
  • Removed friction around manual look-up of IntegerID for Service Accounts by removing the need to use a service_account_int_id TF variable. If you are using the confluentcloud_kafka_acl resource you might see an input validation error after running terraform plan, which can be resolved by following this guide. Updated “Sample project” guide to reflect this change.
  • Simplified confluentcloud_role_binding resource creation by adding a new rbac_crn attribute for confluentcloud_kafka_cluster resource. Updated the confluentcloud_role_binding resource examples to reflect this simplified approach.

UI navigation update
The UI has been updated to show you more information with fewer clicks, and to logically group common actions. Many administrative actions and support links are always available by clicking on your name in the upper-right corner. These options were previously available in the navigation bar and in the cluster management UI. The Quick Start for Confluent Cloud and related documentation is updated to reflect these changes.
Environment overview
Now you can see provisioned capacity and usage data for all your clusters on the new Environment Overview page. Usage data was previously available in a dedicated Activity page for each cluster.
Parameter changes
In the past, Confluent Cloud allowed users to configure a wide range of topic level configuration parameters. However, some of these parameters aren’t necessary when using a fully managed service. Confluent Cloud now ignores these parameters. Existing users should see no change, as it has been verified that these parameters were never used in practice. For consistency, some configuration parameters in the describe topics/configuration APIs are now read-only.
