Hi @pisko1979

You need to configure "Checkpoints" in order to store the state of jobs on "state backends" which basically supports two types "HashMapStateBackend" (saved in JVM heap memory) and "EmbeddedRocksDBStateBackend" (key-value store):

• https://nightlies.apache.org/flink/flink-docs-release-1.20/docs/ops/state/checkpoints
• https://nightlies.apache.org/flink/flink-docs-release-1.20/docs/ops/state/state_backends/#available-state-backends

Please note this chart doesn't support deploying a key-value store in case you want to use a "EmbeddedRocksDBStateBackend", hence you need to deploy it independently.
