Result Set Streaming Support

Starting with version 2.0.5, the connector uses the result set streaming API to improve the performance in fetching query results. To take advantage of this feature, you must do the following:

• Include and allow the athena:GetQueryResultsStream action in your IAM policy statement. For details on managing Athena IAM policies, see https://docs.aws.amazon.com/athena/latest/ug/access.html.
• If you are connecting to Database through a proxy server, make sure that the proxy server does not block port 444. The result set streaming API uses port 444 on the Database server for outbound communications.
