Improvements​

Improved Handling of Incompatible Custom Resources​

The platform now includes enhanced error handling for Custom Resources (CRs) that are incompatible with their CustomResourceDefinition (CRD). Previously, invalid CRs could cause reconciliation loops that led to operator instability or system unreachability. With this update, the platform gracefully handles these reconciliation failures, preventing disruptions and ensuring the system remains stable even when malformed resources are present.

Bug fixes​

Deployments Not Visible Without Sorting​

Resolved an issue where the Deployments page initially appeared empty, requiring users to manually trigger a sort to view their deployments. This was caused by a frontend error when the property spec.containers[] was configured as empty, resulting in a UI rendering failure. The page now loads and displays deployments correctly by default.

Missing CPU and Memory Metrics​

Fixed an issue where CPU and memory usage values were missing from the Deployments page, occasionally causing deployments to appear empty. This is now resolved, ensuring that deployment lists and their associated resource metrics load correctly without requiring filter adjustments.

Fixed an issue where jobs using Flink 1.19 with the changelog state backend enabled failed to restart from checkpoints or savepoints, even when execution.savepoint-restore-mode: CLAIM was configured. The fix addresses an internal conflict regarding full snapshot enforcement, ensuring jobs can now reliably resume using the changelog state backend.

Missing RBAC Permissions for Resource Finalizers​

Resolved an issue where the Helm chart lacked the necessary RBAC permissions to update resource finalizers when blockOwnerDeletion was enabled (VVP 2.15.1+). This previously blocked upgrades or caused reconciliation failures. The Helm chart now grants the required permissions, ensuring smooth upgrades and correct operator behavior without manual patching.

Fixed a NoSuchMethodError during savepoint recovery for Flink 1.20.1 applications. The issue was caused by an outdated commons-cli version within the flink-shaded-hadoop-2-uber dependency. Dependency handling has been updated to avoid classpath conflicts, ensuring reliable startup and recovery.

Schema Validation Error for flinkFatalExceptionFailEarly​

Resolved a schema validation failure that prevented deployments from being created or updated when flinkFatalExceptionFailEarly was configured. The Custom Resource Definition (CRD) has been updated to include this missing field, allowing the configuration to be applied successfully.

Kafka Connector Failure Missing Jackson Dependencies​

Fixed a runtime ClassNotFoundException in the Flink SQL Kafka connector when using OAuth-based authentication. The connector was missing required Jackson libraries (databind, core, annotations). These dependencies are now included, ensuring OAuth authentication works out of the box.
