How to check if no data were missed

I am running a kafka connector in standalone mode with 1 partition to stream data from couchbase to kafka.
I started streaming from beginning. After no new data to stream, I checked the latest kafa topic offset and I found it was much smaller than bucket offset. Is it normal?

@akizminet welcome to the forum and thanks for your enquiry, someone will reach out to you shortly

Hi Akizminet,

Which Kafka topic are you inspecting?

Can you explain what you mean by the “bucket offset”?
