Table Name Mapping and Topic Mapping Supported During Object File Import for Synchronization from GaussDB to Kafka

Figure 1 Importing an object file

Select Table name mapping or Topic mapping. You can select only one mapping type.

• Example of table name mapping: The first column indicates the table to be synchronized, and the second column indicates the mapped table. If the second column is left empty or the values in the first and second columns are the same, no mapping is performed. Database names cannot be mapped, but schema names and table names can be mapped.

The mapped object names are displayed in the Kafka message body.

• Example of topic mapping: The first column indicates the table to be synchronized, and the second column indicates the topic to which the table data is written. If the second column is left empty, no topic mapping is performed and the data is delivered based on the topic policy selected on the console page.

You are advised to create a mapped topic name in Kafka in advance based on service requirements.
