title: Sequence numbers in dyamodb streams
body: <p>I have a stream enabled dynamodb table. A lambda function consumes this stream. Each record in the dynamodb stream has a SequenceNumber assigned to it. What is its significance?</p>
  <p>Lets say that record1 entered the stream before record2. Does it mean that
  SequenceNumber(record1) &lt; SequenceNumber(record2) ?</p>
