Spanner	docs	1	Spanner is a fully managed database service from Google Cloud that combines relational, key-value, graph, and search capabilities.

Spanner Source

Spanner is a fully managed, mission-critical database service that brings together relational, graph, key-value, and search. It offers transactional consistency at global scale, automatic, synchronous replication for high availability, and support for two SQL dialects: GoogleSQL (ANSI 2011 with extensions) and PostgreSQL.

If you are new to Spanner, you can try to create and query a database using the Google Cloud console.

Available Tools

spanner-sql
Execute SQL on Google Cloud Spanner.
spanner-execute-sql
Run structured and parameterized queries on Spanner.

Requirements

IAM Permissions

Spanner uses Identity and Access Management (IAM) to control user and group access to Spanner resources at the project, Spanner instance, and Spanner database levels. Toolbox will use your Application Default Credentials (ADC) to authorize and authenticate when interacting with Spanner.

In addition to setting the ADC for your server, you need to ensure the IAM identity has been given the correct IAM permissions for the query provided. See Apply IAM roles for more information on applying IAM permissions and roles to an identity.

    my-spanner-source:
        kind: "spanner"
        project: "my-project-id"
        instance: "my-instance"
        database: "my_db"
        # dialect: "googlesql"
