Couchbase CDC 7.2 and Kafka Connector

Kafka Connector

Looking for clarification

Kafka Documentation
https://docs.couchbase.com/kafka-connector/current/delivery-guarantees.html
" The source connector does not guarantee every version of a document will be reflected in the Kafka topic. For example, if a Couchbase document value changes rapidly from V1 → V2 → V3 , or if the connector is not running when the change occurs, the connector is only guaranteed to publish the latest value (V3 ). In other words, changes to the same document may be “deduplicated”, in which case only the latest version is published."

But looking at Change History | Couchbase Docs

It seems Kafka should be able to get all changes depending on the seconds and bytes we setup right?

Hi @dipen_patel,

It seems Kafka should be able to get all changes depending on the seconds and bytes we setup right?

That’s correct. Connector versions 4.1.11 and later are able to stream all available historical versions within that “seconds and bytes” window. The paragraph after the one you quoted alludes to this.

Thanks,
David
