Deployment Defaults#
This section explains how to use deployment defaults to develop a job in fully managed Flink, which can make job development more efficient.
Purpose#
To help users avoid complex parameter configuration in the development process, all parameters are used by default for all deployments.
Procedure#
Log in to Ververica Cloud.
On the Dashboard page, locate the workspace you want to manage, click the title of the workspace or this icon ⋮, and select Open Console.
In the left-side navigation pane of the Console, click Configurations and choose the Deployment Defaults tab.
Fill in the following parameters.
Starting Parameters
Parameter |
Description |
|---|---|
Checkpointing Interval |
The interval at which checkpoints are scheduled. If you do not configure this parameter, the checkpointing feature is disabled. |
Min Interval Between Checkpoints |
The minimum interval between two checkpoints. If the maximum parallelism of checkpoints is 1, this parameter specifies the minimum interval between two checkpoints. |
State Expiration Time |
The period of automatic data cleaning for the state, if not filled in, the default value of the deployment engine version will be used. |
Flink Restart Strategy |
If a task fails and the checkpointing feature is disabled, the JobManager cannot be restarted. If the checkpointing feature is enabled, the JobManager is restarted. Valid values: Failure Rate: The JobManager is restarted if the number of failures within the specified interval exceeds the upper limit. If you select Failure Rate from the Flink Restart Policy drop-down list, you must set the Failure Rate Interval, Max Failures per Interval, and Delay Between Restart Attempts parameters. Fixed Delay: The JobManager is restarted at a fixed interval. If you select Fixed Delay from the Flink Restart Policy drop-down list, you must set the Number of Restart Attempts and Delay Between Restart Attempts parameters. No Restarts: The JobManager is not restarted. This is the default value. |
Deployment name |
Enter the name of the Python job. |
Additional Configuration

Additional Flink parameters |
such as taskmanager.numberOfTaskSlots: 1 |
