Define the CRUD Operation

The JDBC Tee processor can insert, update, or delete data. The processor writes the records based on the CRUD operation defined in a CRUD operation header attribute or in operation-related stage properties.

You can define the CRUD operation in the following ways:

CRUD operation header attribute

You can define the CRUD operation in a CRUD operation record header attribute. The processor looks for the CRUD operation to use in the sdc.operation.type record header attribute.

The attribute can contain one of the following numeric values:

1 for INSERT
2 for DELETE
3 for UPDATE

If your pipeline includes a CRUD-enabled origin that processes changed data, the processor simply reads the operation type from the sdc.operation.type header attribute that the origin generates. If your pipeline uses a non-CDC origin, you can use the Expression Evaluator or a scripting processor to define the record header attribute. For more information about Data Collector changed data processing and a list of CDC-enabled origins, see Processing Changed Data.

Operation stage properties

You define a default operation in the processor properties. The processor uses the default operation when the sdc.operation.type record header attribute is not set.

You can also define how to handle records with unsupported operations defined in the sdc.operation.type header attribute. The processor can discard them, send them to error, or use the default operation.
