title: Boto3-Scan DynamoDB with multiple requests (Limit = 100 records) and get items without duplication
body: <p><strong>Scenario</strong>:</p>
  <p>I want to retrieve items from DynamoDB table which has 200k records, I am trying to get them in multiple requests</p>
  <ul>
  <li>for first request I want 100 records only.</li>
  <li>for second request I want next 100 records, here I don't want the records which are already in first request.</li>
  </ul>
  <p><strong>My implementation</strong>:</p>
  <pre><code>scan_kwargs=None
  if scan_kwargs is None:
      scan_kwargs = {}
  complete = False
  
  while not complete:
      try:
          
          response = table.scan(Limit=10000, **scan_kwargs,
              FilterExpression=Key('timestamp').between(dateFrom, dateTo) 
                  ) 
      except botocore.exceptions.ClientError as error:
          raise Exception('Error')
      next_key = response.get('LastEvaluatedKey')
      scan_kwargs['ExclusiveStartKey'] = next_key
      complete = True if next_key is None else False
  
      if response['Items']:
          for record in response['Items']:
              print(record)
              totalRecords = totalRecords + 1
              if totalRecords &gt; 100:
                  break
      if totalRecords &gt; 100:
          break
  </code></pre>
  <p>From the above code I am only able to get first 100 records for multiple requests.
  But my requirement is to get from 101 to 200 records and ignore first 100 records</p>
  <p>Can anyone help with working examples according to my requirement?</p>
