Reference documentation and code samples for the Cloud Spanner Instance Admin V1 API module Google::Cloud::Spanner::Admin::Instance::V1::InstanceAdmin.
Cloud Spanner Instance Admin API
The Cloud Spanner Instance Admin API can be used to create, delete,
modify and list instances. Instances are dedicated Cloud Spanner serving
and storage resources to be used by Cloud Spanner databases.
Each instance has a "configuration", which dictates where the
serving resources for the Cloud Spanner instance are located (e.g.,
US-central, Europe). Configurations are created by Google based on
resource availability.
Cloud Spanner billing is based on the instances that exist and their
sizes. After an instance exists, there are no additional
per-database or per-operation charges for use of the instance
(though there may be additional network bandwidth charges).
Instances offer isolation: problems with databases in one instance
will not affect other instances. However, within an instance
databases can affect each other. For example, if one database in an
instance receives a lot of requests and consumes most of the
instance resources, fewer resources are available for other
databases in that instance, and their performance may suffer.
