/** The starting position in the data stream from which to start streaming.
* @param Type
* You can set the starting position to one of the following values:
*
* AT_SEQUENCE_NUMBER: Start streaming from the position denoted by the
* sequence number specified in the SequenceNumber field.
*
* AFTER_SEQUENCE_NUMBER: Start streaming right after the position denoted
* by the sequence number specified in the SequenceNumber field.
*
* AT_TIMESTAMP: Start streaming from the position denoted by the time stamp
* specified in the Timestamp field.
*
* TRIM_HORIZON: Start streaming at the last untrimmed record in the shard,
* which is the oldest data record in the shard.
*
* LATEST: Start streaming just after the most recent record in the shard,
* so that you always read the most recent data in the shard.
* @param SequenceNumber
* The sequence number of the data record in the shard from which to start streaming. To
* specify a sequence number, set StartingPosition to
* AT_SEQUENCE_NUMBER or AFTER_SEQUENCE_NUMBER.
* @param Timestamp
* The time stamp of the data record from which to start reading. To specify a time
* stamp, set StartingPosition to Type AT_TIMESTAMP. A time stamp
* is the Unix epoch date with precision in milliseconds. For example,
* 2016-04-04T19:58:46.480-00:00 or 1459799926.480. If a
* record with this exact time stamp does not exist, records will be streamed from the next
* (later) record. If the time stamp is older than the current trim horizon, records will
* be streamed from the oldest untrimmed data record (TRIM_HORIZON).
