/** After you call SubscribeToShard, Kinesis Data Streams sends events
  *             of this type over an HTTP/2 connection to your consumer.
  * @param Records
  *   
  * @param ContinuationSequenceNumber
  *   Use this as SequenceNumber in the next call to SubscribeToShard, with StartingPosition set to
  *                   AT_SEQUENCE_NUMBER or AFTER_SEQUENCE_NUMBER. Use
  *                   ContinuationSequenceNumber for checkpointing because it captures your
  *               shard progress even when no data is written to the shard.
  * @param MillisBehindLatest
  *   The number of milliseconds the read records are from the tip of the stream, indicating
  *               how far behind current time the consumer is. A value of zero indicates that record
  *               processing is caught up, and there are no new records to process at this moment.
  * @param ChildShards
  *   The list of the child shards of the current shard, returned only at the end of the
  *               current shard.
