We are pleased to announce two new features for Amazon Redshift,making it easier for you to control access to your clusters and expanding query capabilities.
Ability to modify cluster accessibility setting. You can now modify your Amazon Redshift cluster at any time, to be accessible from the public Internet or from only within your private VPC. Simply select Modify within the cluster detail page, and select Yes or No for the Publicly Accessible configuration setting. Yes means that the cluster will bear a public IP address that can be accessed from the Internet. No means that the cluster will bear a private IP address that can only be accessed from within your VPC. Either change will require a cluster reboot. For more details please see our documentation. Sort order for NULL values. You can now specify whether NULL values should be ordered first,before non-NULL values, or last, and after non-NULL values in your queries. to memorize more,see the ORDER BY Clause section of the Amazon Redshift Developer Guide.
Amazon Redshift makes it easy to launch a hasty, petabyte-scale data warehouse for less than $1000/TB/year. Get started with a free 2-month trial.
