Instance Admin API
After creating a Client
, you can interact with individual instances for a project.
List Instances
If you want a comprehensive list of all existing instances, make a ListInstances API request with Client.list_instances()
:
instances = client.list_instances()
Instance Factory
To create an Instance
object:
instance = client.instance(instance_id, display_name=display_name)
display_name
is optional. When not provided,display_name
defaults to theinstance_id
value.
You can also use Client.instance()
to create a local wrapper for instances that have already been created with the API, or through the web console:
instance = client.instance(existing_instance_id) instance.reload()
Create a new Instance
After creating the instance object, make a CreateInstance API request with create()
:
instance.display_name = 'My very own instance' instance.create()
Check on Current Operation
NOTE: When modifying an instance (via a CreateInstance request), the Bigtable API will return a long-running operation and a corresponding Operation
object will be returned by create()
.
You can check if a long-running operation (for a create()
has finished by making a GetOperation request with Operation.finished()
:
>>> operation = instance.create() >>> operation.finished() True
NOTE: Once an Operation
object has returned True
from finished()
, the object should not be re-used. Subsequent calls to finished()
will result in a ValueError
.
Get metadata for an existing Instance
After creating the instance object, make a GetInstance API request with reload()
:
instance.reload()
This will load display_name
for the existing instance
object.
Update an existing Instance
After creating the instance object, make an UpdateInstance API request with update()
:
instance.display_name = 'New display_name' instance.update()
Delete an existing Instance
Make a DeleteInstance API request with delete()
:
instance.delete()
Next Step
Now we go down the hierarchy from Instance
to a Table
.
