Error

Error handling is a generic way to handle errors without losing data or failing the Snap execution. You can handle the errors that the Snap might encounter while running the Pipeline by choosing one of the following options from the When errors occur list under the Views tab. The available options are:

• Stop Pipeline Execution: Stops the current pipeline execution when the Snap encounters an error.

• Discard Error Data and Continue: Ignores the error, discards that record, and continues with the rest of the records.

• Route Error Data to Error View: Routes the error data to an error view without stopping the Snap execution.

Learn more about Error handling in Pipelines.

Label*

Default Value: Databricks - Execute
Example: Db_MultiQuery

String

The name for the Snap. You can modify this to be more specific, especially if you have more than one of the same Snap in your Pipeline.

SQL Statements*

Use this fieldset to define your SQL statements, one in each row. You can add as many SQL statements as you need.

SQL statement*

Default Value: None.
Example: create table employee (name String, age BigInt)

String/Expression

Specify the Databricks SQL statement you want the Snap to execute. We recommend you to add a single query in the SQL Statement field. The SQL statement must follow the SQL syntax as stipulated in DLP.

Number of Retries

Default Value: 0
Example: 3

Minimum value: 0

Integer

Specify the maximum number of retry attempts the Snap must make in case there is a network failure and is unable to read the target file. The request is terminated if the attempts do not result in a response.

• If the Number of retries value is set to 0 (the default value), the retry option is disabled, and the Snap does not initiate a retry. The pipeline will not attempt to retry the operation in case of a failure—any failure encountered during the database operation will immediately result in the pipeline failing without any retry attempts to recover from the errors.

• If the Number of retries value is greater than 0, the Snap initiates a download of the target file into a temporary local file. If any error occurs during the download, the Snap waits for the time specified in the Retry interval and then attempts to download the file again from the beginning. After the download is successful, the Snap streams the data from the temporary file to the downstream pipeline. All temporary local files are deleted when they are no longer needed.

Retry Interval (Seconds)

Default value: 1
Example: 3

Minimum value: 1

Integer

Specify the minimum number of seconds the Snap must wait before each retry attempt.

Use Result Query

Checkbox

Select this checkbox to write the SQL statement execution result to the Snap's output view for each successful execution. The output of the Snap is enclosed in the key ResultQuery, and the value will be the actual output produced by the SQL statement. The example Pipeline below depicts the difference between the output previews when this checkbox is selected and when it is not.

This option allows you to effectively track the SQL statement's execution by clearly indicating the successful execution and the number of records affected, if any, after the execution.

Manage Queued Queries

Default Value: Continue to execute queued queries when pipeline is stopped or if it fails.
Example: Cancel queued queries when pipeline is stopped or if it fails

Dropdown list

Select either of the following options from the dropdown list to handle queued SQL queries:

• Continue to execute queued queries when pipeline is stopped or if it fails: Continues the execution of the queued Databricks SQL queries when you stop the Pipeline.

• Cancel queued queries when pipeline is stopped or if it fails: Cancels the execution of the queued Databricks SQL queries when you stop the Pipeline

Snap Execution

Default Value: Execute only
Example: Validate & Execute

Dropdown list

Select one of the three modes in which the Snap executes. Available options are:

• Validate & Execute: Performs limited execution of the Snap, and generates a data preview during Pipeline validation. Subsequently, performs full execution of the Snap (unlimited records) during Pipeline runtime.

• Execute only: Performs full execution of the Snap during Pipeline execution without generating preview data.

• Disabled: Disables the Snap and all Snaps that are downstream from it.
