Amazon Redshift data sharing allows you to share live data across Redshift clusters for read purposes without the complexity and delays associated with data copies and data movement. Redshift already allows you to pause and resume your data sharing consumer clusters on-demand or based on schedule according to your workload demands. With this new capability, producer clusters can also be paused while still allowing data sharing with consumer clusters.
Ability to share data when producer clusters are paused helps you to reduce costs in use cases where workloads on the producer clusters are sporadic or intermittent. For example, data ingestion and processing might happen only a few times in a day or you may have development/test environments where datasets are often static. With this capability, queries accessing shared data on the consumer cluster continue to read data from the Redshift managed storage layer directly. You pay only for the managed storage of the producer cluster when the producer cluster is paused.
The ability to use data sharing when producers clusters are paused is available in all regions where data sharing is available, specifically, US East (N. Virginia) US East (Ohio), US West (N. California), US West (Oregon), Asia Pacific (Mumbai), Asia Pacific (Seoul) , Asia Pacific (Singapore) , Asia Pacific (Sydney), Asia Pacific (Tokyo), Canada (Central) , Europe (Frankfurt) , Europe (Ireland) , Europe (London), Europe (Paris) , Europe (Stockholm) and South America (São Paulo). Customers with Amazon Redshift clusters that have Enhanced VPC Routing (EVR) enabled can leverage this capability from version 1.0.25433 onwards.
