You can read data from tables enabled for
data sharing in Amazon Redshift. Data sharing allows you to share data across Amazon Redshift
clusters without the need to copy or move the data or duplicate the storage.
Amazon Redshift
data sharing includes the following components:
Producer cluster. The Amazon Redshift
cluster that owns the data and shares it with other clusters.
Consumer cluster. The Amazon Redshift
cluster that receives and accesses the shared data from a producer cluster.
Datashare. A logical unit of sharing
created on the producer cluster and contains the specific database objects to be
shared.
To use data sharing, specify the database name of the consumer cluster in the JDBC URL
when you create an Amazon Redshift V2 connection.
