warning

Known Issue — FlinkSQL Checkpoint Toggle

Affected Versions: 2.15.0, 2.15.1

Using the Disable Checkpoints toggle in FlinkSQL jobs sets an invalid empty value for execution.checkpointing.interval, causing job deployment failures with errors like:

IllegalArgumentException: Could not parse value '' for key 'execution.checkpointing.interval'

Workaround: Instead of disabling checkpoints through the toggle, explicitly set the checkpoint interval to the maximum possible integer value:

execution.checkpointing.interval: 9223372036854775807ms

Features​

Restore Deployments from a Savepoint via the Kubernetes Operator​

Now the Ververica Platform Kubernetes Operator can start a deployment directly from a Flink savepoint. Add the field below when you create a VvpDeployment manifest:

spec:
  initialSavepointSpec:
    savePointLocation: s3://bucket/path/to/savepoint-abc123

Key conditions:

  • The savepoint status must be COMPLETED.
  • The deployment’s current state must be spec.deployment.spec.state: CANCELLED.
  • spec.deployment.restoreStrategy must not be NONE.
  • The deployment must not already exist.

This one-line addition enables one-shot recoveries and disaster-recovery drills through GitOps alone, bringing the operator to par with the UI and REST API.

Improvements​

Audit Log Captures Login Activity​

The Audit Log now also records:

  • Successful user logins
  • User logouts
  • Failed / denied login attempts

These entries appear alongside all other audit records in the UI and via the REST API, so admins can filter or export them for GDPR and internal-security reviews. No configuration changes are required — every new and existing namespace inherits the extended logging automatically.

Bug Fixes​

Events Tab Fixed — Shows Timestamps, Right Job IDs, and Works Without the Operator​

In 2.15.0, the Kubernetes Events tab could look incomplete — timestamps were missing, Job IDs showed an internal handle, and the list stayed empty if the VVP Kubernetes Operator was turned off because the platform pod lacked the right RBAC. The 2.15.1 release corrects all three in one go: the timestamp column is filled, the proper Flink Job ID appears, and the platform role now includes the needed get/list/watch permissions so events load even without the operator.

Missing metadata.ownerReferences on Deployment Created by Ververica Kubernetes Operator​

In previous versions, metadata.ownerReferences was not populated properly leading to a broken chain of ownership in Kubernetes resources. This release fixes the assignment of metadata.ownerReferences by Ververica Platform to point to the CR that was created via the Kubernetes Operator.
