Changes Amazon Redshift now supports operations to pause and resume a cluster on demand or on a schedule.
Changes Extend elastic resize to support resizing clusters to different instance types.
Changes This release contains changes for 1. Redshift Scheduler 2. Update to the DescribeNodeConfigurationOptions to include a new action type recommend-node-config
Changes Adds API operation DescribeNodeConfigurationOptions and associated data structures.
Changes Add expectedNextSnapshotScheduleTime and expectedNextSnapshotScheduleTimeStatus to redshift cluster object.
Changes ClusterAvailabilityStatus: The availability status of the cluster for queries. Possible values are the following: Available, Unavailable, Maintenance, Modifying, Failed.
Changes DescribeResize can now return percent of data transferred from source cluster to target cluster for a classic resize.
Changes DescribeSnapshotSchedules returns a list of snapshot schedules. With this release, this API will have a list of clusters and number of clusters associated with the schedule.
Changes With this release, Redshift is providing API's for better snapshot management by supporting user defined automated snapshot schedules, retention periods for manual snapshots, and aggregate snapshot actions including batch deleting user snapshots, viewing account level snapshot storage metrics, and better filtering and sorting on the describe-cluster-snapshots API. Automated snapshots can be scheduled to be taken at a custom interval and the schedule created can be reused across clusters. Manual snapshot retention periods can be set at the cluster, snapshot, and cross-region-copy level. The retention period set on a manual snapshot indicates how many days the snapshot will be retained before being automatically deleted.
Changes Amazon Redshift provides the option to defer non-mandatory maintenance updates to a later date.
Changes Adding support to Redshift to change the encryption type after cluster creation completes.
Changes You can now resize your Amazon Redshift cluster quickly. With the new ResizeCluster action, your cluster is available for read and write operations within minutes
Changes When we make a new version of Amazon Redshift available, we update your cluster during its maintenance window. By selecting a maintenance track, you control whether we update your cluster with the most recent approved release, or with the previous release. The two values for maintenance track are current and trailing. If you choose the current track, your cluster is updated with the latest approved release. If you choose the trailing track, your cluster is updated with the release that was approved previously.The new API operation for managing maintenance tracks for a cluster is DescribeClusterTracks. In addition, the following API operations have new MaintenanceTrackName parameters: Cluster, PendingModifiedValues, ModifyCluster, RestoreFromClusterSnapshot, CreateCluster, Snapshot
Changes Feature 1 - On-demand cluster release version - When Amazon Redshift releases a new cluster version, you can choose to upgrade to that version immediately instead of waiting until your next maintenance window. You can also choose to roll back to a previous version. The two new APIs added for managing cluster release version are - ModifyClusterDbRevision, DescribeClusterDbRevisions. Feature 2 - Upgradeable reserved instance - You can now exchange one Reserved Instance for a new Reserved Instance with no changes to the terms of your existing Reserved Instance (term, payment type, or number of nodes). The two new APIs added for managing these upgrades are - AcceptReservedNodeExchange, GetReservedNodeExchangeOfferings.
Changes DescribeClusterSnapshotsMessage with ClusterExists flag returns snapshots of existing clusters. Else both existing and deleted cluster snapshots are returned
Changes DescribeEventSubscriptions API supports tag keys and tag values as request parameters.
Changes This update adds the GetClusterCredentials API which is used to get temporary login credentials to the cluster. AccountWithRestoreAccess now has a new member AccountAlias, this is the identifier of the AWS support account authorized to restore the specified snapshot. This is added to support the feature where the customer can share their snapshot with the Amazon Redshift Support Account without having to manually specify the AWS Redshift Service account ID on the AWS Console/API.
Changes This release of Amazon Redshift introduces Enhanced VPC Routing. When you use Amazon Redshift Enhanced VPC Routing, Amazon Redshift forces all COPY and UNLOAD traffic between your cluster and your data repositories through your Amazon VPC.
