Modify deployment default settings

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

1. On the Dashboard page, open the console for the workspace you want to manage.

2. In the Console navigation pane, click Configurations and choose the Deployment Defaults tab.

3. Fill in the starting parameters. All parameters are listed below.

4. Click Save Changes.

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

Parameter	Description
Additional Flink parameters	such as taskmanager.numberOfTaskSlots: 1

Logging

Parameter	Description
Allow Log Archives	By default, Allow Log Archives is turned on. After Allow Log Archives is turned on in the Logging section, you can view the logs of a historical job instance on the Logs tab. For more information, see View the logs of a historical job instance.
Log Archives Expires(Unit: day)	By default, the archived log files are valid for seven days.
Root Log Level	You can specify the following log levels. The levels are listed in ascending order of urgency. TRACE: records finer-grained information than DEBUG logs. DEBUG: records the status of the system. INFO: records important system information. WARN: records the information about potential issues. ERROR: records the information about errors and exceptions that occur.
Log Levels	Enter the log name and log level.
