The performance of the queries on shared data depends on the compute capacity of the consumer clusters. The producer is charged for the underlying storage of data in their provisioned cluster or serverless namespace. The consumer is charged for all compute and cross-region data transfer fees required to query the producer's data. You can't connect to the databases created from a datashare but can read from those databases. Within the same cluster, you can query another database using simple three-part notation as long as you have the required privileges on the objects in the other database.Īs a datashare user, you continue to connect to your local cluster database only. You only need datashares when you are sharing data between different Amazon Redshift provisioned clusters or serverless workgroups. You can use AWS Data Exchange datashares to license query access to your data via AWS Data Exchange. You can share between cluster types as well as between provisioned clusters and serverless.Ĭross-Region data sharing comes with additional cross-region data transfer charges. You can share data across provisioned clusters, serverless workgroups, Availability Zones, AWS accounts, and AWS Regions. ![]() (ra3.16xlarge, ra3.4xlarge, and ra3.xlplus) and Amazon Redshift Serverless. We use comprehensive emission-line catalogues of galaxies from the IllustrisTNG simulation including ionization by stars, active nuclei and shocks to reassess the calibrations of both optical and ultraviolet metallicity estimators at redshifts. ![]() Amazon Redshift data sharing is supported for all provisioned ra3 cluster types
