- If no Kinesis checkpoint info exists when the input DStream starts, it
will start either from the oldest record available
(`InitialPositionInStream.TRIM_HORIZON`) or from the latest tip
(`InitialPositionInStream.LATEST`). This is configurable.
- `InitialPositionInStream.LATEST` could lead to missed records if data
is added to the stream while no input DStreams are running (and no checkpoint
info is being stored).
- `InitialPositionInStream.TRIM_HORIZON` may lead to duplicate
processing of records where the impact is dependent on checkpoint frequency and
processing idempotency.

between Kinesis retries (in milliseconds). Default is "100ms".

`SparkConf for` is redundant. I would try to focus on when should people
actually tweak these, why are these confs important in the first place
