If the `arg` variable is set, adds `--<arg> <name>` to the arguments passed to the job If `arg` is not set, adds `--<type>-kafka-topic <name>` or `--<type>-kafka-topic-<postfix> <name>` See [values.yaml](values.yaml) for the format |
 | job.parallelism | int | `1` | How many jobs to run in parallel, see more here: <https://nightlies.apache.org/flink/flink-docs-master/docs/dev/datastream/execution/parallel/> |
 | job.state | string | `"running"` | Desired state of the job. Must be either: `running` or `suspended` |
-| job.upgradeMode | string | `"savepoint"` | Application upgrade mode. Must be either: stateless, last_state, savepoint `stateless` upgrades is done from an empty state `last-state` does a quick upgrade. Does not require the job to be in a healthy state, as it makes use of the HA metadata `savepoint` makes use of savepoints when upgrading and requires the job to be running.
