title: How DynamoDB keeps itself in sync with all regions
body: <p>I am creating one dynamoDB table using serverless.yml, this table will get created in multiple regions.</p>
  <pre><code>FreeTrailUsersDynamoDbTable:
    Type: AWS::DynamoDB::Table
    Properties:
      PointInTimeRecoverySpecification:
        PointInTimeRecoveryEnabled: true
      AttributeDefinitions:
        - AttributeName: id
          AttributeType: S
      KeySchema:
        - AttributeName: id
          KeyType: HASH
      BillingMode: PAY_PER_REQUEST
      TableName: ${self:custom.config.prefix}-free-trail-users
  </code></pre>
  <p>Now I want to know. How DynamoDB will keep upto date itself with different regions. Will creation on record in one region will get sync in other region.</p>
  <p>Do I need to do extra thing from my side to these sync to happen ??</p>
