Define the CRUD Operation

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

You define the CRUD operation in the following ways:

CRUD record header attribute

The destination looks for the CRUD operation 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
• 4 for UPSERT

If your pipeline has a CRUD-enabled origin that processes changed data, the destination simply reads the operation type from the sdc.operation.type header attribute that the origin generates. If your pipeline has a non-CDC origin, you can use the Expression Evaluator processor 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

If there is no CRUD operation in the sdc.operation.type record header attribute, the destination uses the operation configured in the Default Operation property.

If the sdc.operation.type record header attribute contains an unsupported value, the destination takes the action configured in the Unsupported Operation Handling property. The destination can discard the record, send the record for error handling, or write the record using the default operation.
