• You can press Ctrl+S to save notebook jobs.

Allows you to create a paragraph. You can also move the pointer over the middle part between two paragraphs and click +Create Paragraph.

Allows you to run code in all paragraphs.

Allows you to pause the execution of code in all paragraphs.

Allows you to clear the results of all paragraphs.

Allows you to configure startup parameters for a notebook job. For more information, see Spark application configuration parameters.

Example:

{
        "spark.driver.resourceSpec": "small",
        "spark.executor.instances": 2,
        "spark.executor.resourceSpec": "small",
        "spark.adb.eni.vswitchId":"vsw-bp14pj8h0k5p0kwu3****",
