Hi @Jose Gonzalez​ ,

Thanks for sharing the document. I would like to share my understanding from the document. Please correct me if I'm wrong.

minFetchPeriod is the time interval between consecutive pre-fetch between kinesis and spark. maxFetchDuration is the how long the pre-fetched data will be stored in buffer. In my case, after 60s data will be available to process.

But how the data from kinesis is pre-fetched?
