The default output view contains the data fetched by running the SELECT statement on the source location.

A second view can be added to show the metadata for the table as a Document. The metadata document can then be fed into the second input view of Databricks - Merge Into or Bulk Load Snaps so that the table is created in Databricks with a similar schema as the source table.

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 - Select
Example: DLP Select

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.

Database name

Default Value: N/A
Example: SalesDB

String/Expression/Suggestion

Enter your DLP database name for the SELECT statement to read the data from.

Table name*

Default Value: N/A
Example: leads_to_sales_conversion

String/Expression/Suggestion

Enter your table name for the SELECT statement to read the data from.

Where clause

Default Value: N/A
Example: LEAD_CITY=Delware

String/Expression/Suggestion

Specify the WHERE clause (condition) for the SELECT statement to apply while retrieving the data from the DLP table.

Order by

You can use this fieldset to define the order in which the retrieved rows are populated in the output. Click the Add fieldset row icon ( ) and specify one column name in each row to define your sort order.

Column names

Default Value: None.
Example: LEAD_REGION

String/Expression/Suggestion

Click the Suggest icon ( ) and select a column name from the suggested list of column names in the table specified above.

Limit rows

Default Value: None.
Example: 100

String/Expression

Specify the number of rows of data you want the Snap to retrieve from the table.

Output fields

You can use this fieldset to define the list of columns to be retrieved in the output. Click the Add fieldset row icon ( ) and specify one column name in each row.

Output field

Default Value: None.
Example: LEAD_EXP_VALUE

String/Expression/Suggestion

Click the Suggest icon ( ) and select a column name from the suggested list of column names in the table specified above.

Fetch Output Fields In Schema

Default Value: Not selected
Example: Selected

Checkbox

Select this checkbox to retrieve schema information from the table for only the output fields specified above. If not selected, the Snap retrieves schema information from all fields available in the table.

Pass through

Default Value: Selected
Example: Not selected

Checkbox

Select this checkbox to include the input document as-is under the original key of this Snap's output.

Ignore empty result

Default Value: Not selected
Example: Selected

Checkbox

Select this checkbox to prevent the Snap from writing any document to its output view when no records are retrieved for the specified Snap configuration.

Match data types

Default Value: Not selected
Example: Selected

Checkbox

With at least one output field selected in the Output fields fieldset, select this checkbox to match the data types of the columns with those retrieved when no output field is specified (as in SELECT * FROM... ). The output preview will be in the same format as the one when the statement SELECT * FROM <specified_table> is run and all the contents of the table are displayed.

Number of Retries

Default value: 0

Example: 3

Minimum value: 0

Integer

Specifies the maximum number of retry attempts when the Snap fails to write.

Retry Interval (seconds)

Default value: 1

Example: 3

Minimum value: 1

Integer

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

Staging Mode

Default value: In Memory

Example: On disk

Dropdown list

Select this property to specify the location where the in-flight records should be stored while using the Retry option. Options available are:

On disk: The records are stored on the disk.

In Memory: The records are stored in the internal memory.

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 this property to determine whether the Snap should continue or cancel the execution of the queued Databricks SQL queries when you stop the Pipeline.

Snap Execution

Default Value: Validate & Execute
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.

Missing property value

You have not specified a value for the required field where this message appears.

Ensure that you specify valid values for all required fields.

Account Settings for Databricks - Select Snap

Notes

We configure the Snap to fetch the table schema (output1) and the table data (rows) from the example_company_employees table in the DLP instance.

The Snap uses a Databricks JDBC driver and the corresponding basic auth credentials to connect to the Databricks instance hosted on the AWS cloud.

Account Settings for Snowflake - Insert Snap

Notes

We configure the Snap to consume the table schema (output1) and the table data (rows) from the example_company_employees table in the DLP instance.

The Snap uses a Snowflake JDBC driver and the corresponding basic auth credentials to connect to the Snowflake (target) instance hosted on the AWS cloud.

The Snap is configured to perform the Insert operation only during Pipeline execution and hence, it does not display any results during validation. Upon Pipeline Execution, the Snap creates a new table example_company_employees in the specified Snowflake database using the schema from the Databricks - Select Snap and populates the retrieved rows data in this new table.
