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:
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. |

Snowflake stage folder.
This field is available when you select Internal from the Storage drop-down list in the Basic settings view. |
Put Command Error Retry | Specify the maximum data loading retries when an error occurs during loading
data to the internal Snowflake storage. This parameter defaults to 3. A value of

-1 or positive integers are accepted. This field is available when you select Internal from the Storage drop-down list in the Basic settings view. |
S3 assume role |
If you temporarily need some access permissions associated to an AWS IAM role that is not granted to your user account, select this check box to assume that role. Then specify the values for the following parameters to create a new assumed role session. Ensure that access to this role has been granted to your user account by the trust policy associated to this role. If you are not certain about this, ask the owner of this role or your AWS administrator. Information noteNote:
|
S3 Max Error Retry | Specify the maximum data loading retries when an error occurs during loading
data to or from the S3 folder. This parameter defaults to 3. A value of
-1 specifies the maximum possible retries. Only
-1 or positive integers are accepted. This field is available when you select S3 from the Storage drop-down list in the Basic settings view. |
Azure Max Error Retry | Specify the maximum data loading retries when an error occurs during loading
data to or from the Azure folder. This parameter defaults to 3. A value of

Non-empty Storage Folder Action | Specify the action to be performed when the storage folder specified for uploading data is not empty.
|
Chunk Size (bytes) | Specify the size for the files generated, which defaults to 52428800
bytes. 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. This option can significantly affect the performance. So set it carefully. See File Sizing Best Practices and Limitations for related information. |
Use Custom Local Folder | Specify a local folder as a temporary folder for holding the files generated. With this option selected, files for storing the incoming data are first generated in the specified local folder and are then moved to the specified storage after all the incoming data is uploaded. |
Number of file requests threads | Specify the number of threads used for sending Put requests in parallel when writing the data in the files. |
