§Properties

database?: string

[src]

Cloud Spanner database in the form `project/instance/database'

databaseRole?: string

[src]

Optional. Cloud Spanner database role for fine-grained access control. The Cloud Spanner admin should have provisioned the database role with appropriate permissions, such as SELECT and INSERT.

useDataBoost?: boolean

[src]

If set, the request will be executed via Spanner independent compute resources. REQUIRES: use_parallelism must be set.

useParallelism?: boolean

[src]

If parallelism should be used when reading from Cloud Spanner
