Table

Click the [...] button and in the displayed wizard, select the Snowflake table to be used.

To load the data into a new table, select Use custom object in the wizard and enter the name of the new table in Object Name field.

Schema and Edit Schema

A schema is a row description. It defines the number of fields (columns) to be processed and passed on to the next component. When you create a Spark Job, avoid the reserved word line when naming the fields.

Built-In: You create and store the schema locally for this component only.

Repository: You have already created the schema and stored it in the Repository. You can reuse it in various projects and Job designs.

If the Snowflake data type to be handled is VARIANT, OBJECT, or ARRAY, while defining the schema in the component, select String for the corresponding data in the Type column of the schema editor wizard.

Click Edit schema to make changes to the schema. If the current schema is of the Repository type, three options are available:

• View schema: choose this option to view the schema only.

• Change to built-in property: choose this option to change the schema to Built-in for local changes.

• Update repository connection: choose this option to change the schema stored in the repository and decide whether to propagate the changes to all the Jobs upon completion.

  If you just want to propagate the changes to the current Job, you can select No upon completion and choose this schema metadata again in the Repository Content window.

Note that if the input value of any non-nullable primitive field is null, the row of data including that field will be rejected.

This component offers the advantage of the dynamic schema feature. This allows you to retrieve unknown columns from source files or to copy batches of columns from a source without mapping each column individually. For further information about dynamic schemas, see Dynamic schema.

This dynamic schema feature is designed for the purpose of retrieving unknown columns of a table and is recommended to be used for this purpose only; it is not recommended for the use of creating tables.

• NONE: Leave the table as is.
• DROP_CREATE: Remove the table and create it again.
• CREATE: Create a new table.
• CREATE_IF_NOT_EXISTS: Create the table if it does not exist.
• DROP_IF_EXISTS_AND_CREATE: Remove the table if it already exists and create again.
• CLEAR: Remove all the data records in the table.
• TRUNCATE: Remove all the rows in the table. This action releases the space occupied by the table.

• INSERT: Insert new records in the Snowflake table.
  Information noteNote: Because this operation uses the Snowflake COPY INTO command, which drops the use of temporary tables and currently does not support data validation, unexpected results may occur when you retrieve rejected records. See Transforming Data During a Load for related information.
• UPDATE: Update existing records in the Snowflake table.
• UPSERT: Create new records and update existing records. You need to specify a schema column as the join key from the Upsert Key Column drop-down list or specify to use the schema keys for the operation by selecting Use schema keys for upsert in the Advanced settings view.
  Information noteNote: The Upsert Key Column drop-down list is available when Use schema keys for upsert is not selected.
• DELETE: Remove records from the Snowflake table.

• Add New Files: continues to process the Job even if the selected storage folder already contains files and adds new files to the folder.
• Cancel Upload: stops the operation when the storage folder used for loading data is not empty.
• Replace Existing Files: cleans the storage folder before adding new files.

With this option specified, the incoming data may be stored in multiple files. Since data is stored in files on a record base, the actual size of each file generated can be larger or smaller than the specified value, but no more than the size of the last record stored in the file.
