Field Name | Field Type | Description |
|---|
Label* Default Value: AlloyDB Bulk Load
Example: Load Employee Data | String | Specify a unique name for the Snap. |
Schema Default Value: N/A
Example: Employee | String/Expression | Specify the database schema name in AlloyDB. If you do not specify a schema, then the suggestion for the Table name retrieves all table names of all schemas. |
Table name*
Default Value: N/A
Example: Employee.PersonnelInformation
| String/Expression | Specify the AlloyDB table on which to run the bulk load operation. |
|---|
Create table if not present
Default Value: Deselected
| Checkbox | Select this checkbox to automatically create the target table if it does not exist. If a second input view is configured for the Snap and it contains a document with schema (metadata) of the source table, the Snap creates the new (target) table using the same schema (metadata). However, if the schema comes from a different database, the Snap might fail with Unable to create table: "<table_name>" error due to data type incompatibility. In the absence of a second input view (the schema/metadata document), the Snap creates a table based on the data types of the columns generated from the first row of the input document (first input view).
| Note |
|---|
A newly created table is not visible to subsequent database Snaps during runtime validation. If you want to immediately use the newly updated data you must use a child Pipeline that is invoked through a Pipeline Execute Snap. |
|
Columns | Use this field set to define the columns to be loaded/copied. If you do not configure this field set, then all columns in the input data stream are loaded into the target table. You can also set how you want the Snap to handle null values for each column. | Note |
|---|
Column order is critical when using the binary input view. You can select both Force Non-Null and Force Null simultaneously. In such cases, the Snap converts quoted null strings to null values and unquoted null strings to empty strings.

|
Column
Default Value: N/A
Example: emp_name
| String/Expression | Specify the name of the column/field. This is a suggestible field and lists all field names in the input. |
Force Not-Null
Default Value: Deselected
Example: N/A
| Checkbox | Select this checkbox to not match the selected column's value against the null string. The Snap reads empty null strings as zero-length strings rather than nulls, even when they are not quoted. |
Force Null
Default Value: Deselected
Example: N/A
| Checkbox | Select this checkbox to match the selected column value against the null string, even if it has been quoted. If a match is found, the field value is set to NULL. By default, when the null string is empty, the Snap converts a quoted empty string into NULL. |
Format*
Default Value: Text
Example: CSV
| Dropdown list | Choose the data format to be written. This field is applicable only when using the binary input view. Text - tab-separated-values (default) CSV - comma-separated-values Binary - AlloyDB specific format
|
Header Provided
Default Value: Deselected
Example: N/A
| Checkbox | Select this checkbox to include the input data as a header. Applicable only when using the binary input view and CSV option in the Format field. |
Encoding Default Value: UTF8
Example: Unicode | Dropdown list | Choose one of the following encodings to use. This is limited to the encodings supported by the AlloyDB server: | Expand |

Snap Execution Default Value:
Example: Validate & Execute | Dropdown list | Select one of the following three modes in which the Snap executes: 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 runtime without generating preview data. Disabled: Disables the Snap and all Snaps that are downstream from it.
