Sync to Kafka is similar to data subscription because both features can be used to obtain real-time data changes in the source database, and therefore can be applied in data archiving, data analysis, and other scenarios.
If you have a CKafka instance, or if you need to sync the full + incremental data of the source database, we recommend that you select the sync to Kafka feature.
If you don't have a CKafka instance, and you only need to obtain the incremental database/table data changes of the source database, we recommend that you select data subscription (Kafka edition).
If both features can meet your business needs, we recommend that you select the most cost-effective solution by referring to their billing details in Billing Overview.
