> Currently, watermarks in kinesis IO are computed taking into account the
> record arrival time in a {{KinesisRecord}}. The arrival time might not always
> be the right representation of the event time. The user of the IO should be
> able to specify how they want to extract the event time from the
> KinesisRecord.
> As the per current logic, the end user of the IO cannot control watermark
> computation in any way. A user should be able to control watermark
> computation through some custom heuristics or configurable params like time
> duration to advance the watermark if no data was received (could be due to a
> shard getting stalled. The watermark should advance and not be stalled in
> that case).
