Big Data Instance

Big Data Instances are database instances which store and process big data. An example of this type of instance would be AWS Redshift. This class inherits from TopLevelResource and has direct access to the resource’s database object. The following attributes are directly accessible:

attr resource_id:
 The primary resource identifier that takes the form of a prefix followed by numbers and letters
attr organization_service_id:
 The ID of the parent organization service (cloud)
attr region_name:
 The region that the instance resides in
attr instance_id:
 The provider ID of the instance
attr name:The name of the instance
attr instance_type:
 The type of instance
attr instance_flavor_resource_id:
 The resource ID of the type (flavor) this instance runs on
attr state:The state of the big data instance
attr availability_zone:
 The zone where the big data instance lives
attr endpoint_address:
 The FQDN of the big data instance
attr endpoint_port:
 The port that the big data instance listens on
attr version:The software version the big data instance leverages
attr db_name:The name of the master database
attr backup_retention:
 An integer representing the number of days that automatic snapshots are retained for
attr master_username:
 The username of the master user
attr encrypted:Denotes if the data stored on the instance is encrypted
attr publicly_accessible:
 Denotes if the instance can be accessed over the Internet
attr access_lists:
 Returns a list of associated security groups
attr instance_flavor:
 Returns a flavor object which contains information on the size of the instance

Big data instance operations

delete(wait_for_result=True, user_resource_id=None)
Delete this resource. If wrapped in a with JobQueue() block, this will queue the deletion job to the wrapped queue, otherwise it
calls immediately.
static get_db_class()

Retrieve the instance type of the resource

static get_provider_id_field()
static get_resource_type()

Retrieve the instance state

handle_resource_created(user_resource_id=None, project_resource_id=None)

This should be called when a resource is created/discovered after the basic data is added to the database. This gives an opportunity for post-addition hooks (assignment to projects/groups, alerts, etc)

handle_resource_destroyed(user_resource_id=None, project_resource_id=None)

This should be called when a resource is destroyed before the basic data is removed from the database. This gives an opportunity for pre-destruction hooks (removal from projects/groups, alerts, etc)

handle_resource_modified(resource, *args, **kwargs)

This should be called when a resource is modified after the new data has been updated in the DB session This gives an opportunity for post-modification hooks
