Redshift Schema

datashare

The datashare block describes a datashare created in this database, and the consumers granted access to it. A function is shared by name: Redshift does not report which of its overloads a datashare holds, so every overload is added to and removed from the share together.

datashare "sales_share" {
  public_accessible = false
  schema {
    for     = schema.sales
    objects = [table.orders, view.summary]
  }
  schema {
    for         = schema.logs
    include_new = true
  }
  schema {
    for                = schema.events
    include_new_except = [table.audit]
  }
  namespaces = ["00000000-0000-0000-0000-000000000000"]
  accounts   = ["000000000000"]
}

datashare attributes

Name and description	Required	Value
accounts AWS account IDs of the consumers granted usage on the datashare. Used for a consumer in another account, which then grants its own namespaces.	false	List of strings
namespaces Namespace identifiers of the consumers granted usage on the datashare. Used for a consumer in the same AWS account.	false	List of strings
public_accessible	false	bool

datashare blocks

datashare.schema

A schema shared by the datashare, and the objects shared from it.

datashare.schema attributes

Name and description	Required	Value
for	true	Object reference to schema
include_new Share every object of the schema, including the ones created later. Redshift shares only the objects created after this is set, so the ones that already exist are shared by Atlas.	false	bool
include_new_except Share every object of the schema except these. Implies include_new.	false	List of values, where each can be one of: Object reference to table Object reference to view Object reference to materialized Object reference to function
objects	false	List of values, where each can be one of: Object reference to table Object reference to view Object reference to materialized Object reference to function
