Regions specify the cloud and cloud-region where user's streaming stores such as Apache Kafka and Kinesis are accessed from and where DeltaStream queries are run.
When creating a DeltaStream Store, an access_region must be specified. All Queries which use the Store will be run in the specified access_region. While it is possible to use an access_region which is different from the cloud/region hosting the database, this will incur additional cost and latency due to cross-region traffic.
As an example, if 'us-west-1' is specified as the access region when creating an MSK store, all the queries in DeltaStream that read and write from this store will be run in 'us-west-1' region.
Use the SHOW REGIONS command to get a list of supported access_regions.
