Apache Kafka SQL Connector: Scan Source: bounded support?

[ravi_suryavanshi.yahoo.com via user]

Hi,We are currently evaluating the Apache Kafka SQL Connector. According to the 
Flink v2.0.1 documentation, a Kafka Scan Source can be used as an unbounded 
source. However, we also noticed the scan.bounded.mode option, and when this 
option is enabled, the Flink job runs in batch mode.
We would like to confirm whether batch mode is officially supported for the 
Kafka SQL Connector. If it is supported, what behavior should we expect when 
using the different bounded modes: latest-offset, group-offsets, timestamp, and 
specific-offsets?
In our tests, latest-offset returns old events, while timestamp returns no 
events.
