Bug Fixes
-
Due to a regression in Ververica Platform 2.0, Deployments with restore strategy
LATEST_STATE
did behave exactly as with restore strategyLATEST_SAVEPOINT
. This is now fixed for Deployments using Flink Jobmanager Failover with Kubernetes. We recommend users relying on restore strategyLATEST_STATE
to switch from Zookeeper to Kubernetes for Flink Jobmanager failover (see also Requirements for LATEST_STATE). -
In the course of this bugfix,
LATEST_STATE
restore strategy was improved to become more explicit and transparent for users: as before this restore strategy relies on Apache Flink® retained checkpoints. These are now listed in the "Snapshots"-tab (formerly "Savepoints") of the web user interface, just like regular savepoints. By this, users can now manually reset their Deployments to retained checkpoints, too, and - more importantly - users can always see if a Deployment will recover from a retained checkpoint when using restore strategyLATEST_STATE
. Please see Requirements for LATEST_STATE for details. -
Quotation marks in
Deployment.spec.template.spec.artifact.mainArgs
are handled more robustly now. See Deployment Templates for details.
