Class CloudSpannerProperties (1.12.1)

CloudSpannerProperties(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Connection properties specific to Cloud Spanner.


database str
Cloud Spanner database in the form \`project/instance/database'
use_parallelism bool
If parallelism should be used when reading from Cloud Spanner
use_serverless_analytics bool
If the serverless analytics service should be used to read data from Cloud Spanner. Note: use_parallelism must be set when using serverless analytics.
database_role str
Optional. Cloud Spanner database role for fine-grained access control. A database role is a collection of fine-grained access privileges. Example: Admin predefines roles that provides user a set of permissions (SELECT, INSERT, ..). The user can then specify a predefined role on a connection to execute their Cloud Spanner query. The role is passthrough here. If the user is not authorized to use the specified role, they get an error. This validation happens on Cloud Spanner. See for more details. REQUIRES: database role name must start with uppercase/lowercase letter and only contain uppercase/lowercase letters, numbers, and underscores.
