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: Snowflake - Update
Example: Snowflake - Update

String

Specify 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.

Schema Name

Default Value: N/A
Example: "PUBLIC"

String/Expression/Suggestion

Specify the database schema name. In case it is not defined, then the suggestion for the Table Name will retrieve all tables names of all schemas. The property is suggestible and will retrieve available database schemas during suggest values.

Table Name*

Default Value: N/A
Example: Employee

String/Expression/Suggestion

Specify the name of the table in the instance. The table name is suggestible and requires an account setting.  

Update condition

Default Value: N/A
Example:

Without using expressions

• EmpId = 12 

• email = 'you@example.com'

Using expressions

• "EMPNO=$EMPNO and ENAME=$EMPNAME"

• email = $email 

• emp=$emp

• "emp='" + $emp + "'"

• "EMPNO=" + $EMPNO + " and ENAME='" + $EMPNAME+ "'"

String/Expression

Specify the SQL WHERE clause of the update statement. You can define specific values or columns to update (Set condition) in the upstream Snap, such as Mapper Snap, and then use the WHERE clause to apply these conditions on the columns sourced from the upstream Snap. For instance, here is a sample of an Update SQL query:
UPDATE table_name
SET column1 = value1, column2 = value2,
WHERE condition;

Open

Refer to the example to understand how to use the Update Condition.

Number of retries

Default Value: 0
Example: 3

Integer/Expression

Specify the maximum number of attempts to be made to receive a response. The request is terminated if the attempts do not result in a response.

Retry interval (seconds)

Default Value: 1
Example: 10

Integer/Expression

Specify the time interval between two successive retry requests. A retry happens only when the previous attempt resulted in an exception. 

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

Choose an option to determine whether the Snap should continue or cancel the execution of the queued queries when the pipeline stops or fails.

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.
