Is there a way to set a KafkaSource end condition to load data until there are no new data arrivals

Hi,
My goal is to manually copy data into Vertica using a KafkaSource. Apparently, I can define an end condition so that no new data arrives until a timeout period expires.
What is the timeout period and how do I set it?
With a KafkaSource, I can COPY data into Vertica over a defined period of time. Would it be possible to retrieve the Kafka message offset where this COPY statement ended so that the next round begins exactly there?

Yes right after your COPY .... KafkaSource , issue a SELECT KafkaOffsets() OVER () and you will get last consumed offsets per partition,

regarding you timeout question, vertica provides 3 ways to specify the termination condition, Please check the below link.
