Cloud SQL release notes

Cloud SQL for MySQL 9.7 is generally available (GA).

For more information about the differences between MySQL 9.7 and previous versions, review the MySQL 9.7 Release Notes.

By default, if you specify MySQL 9.7 as the version when you create a Cloud SQL instance (either primary or replica) using the gcloud CLI, the Google Cloud console, or the REST API, then the Cloud SQL edition is Cloud SQL Enterprise Plus edition.

This release introduces support for key MySQL 9.7 capabilities, including:

• Vector search: support for the community-standard vector storage format combined with advanced approximate nearest neighbor (ANN) vector indexing in Cloud SQL.
• Hypergraph optimizer: an alternative join-planning framework designed for complex, multi-table queries. You can enable the hypergraph optimizer using an optimizer switch.
• JSON Duality Views: a feature that bridges relational SQL and hierarchical JSON document models to interact with the same underlying data.
• Upgrade and migration paths: support for in-place major version upgrade from Cloud SQL for MySQL 8.4 and migrations from MySQL 8.4 using the Database Migration Service (DMS).

Flag updates for MySQL 9.7

Additionally, this release introduces several database flag changes.

You can now create and query parameterized secure views in Cloud SQL for PostgreSQL.

Parameterized secure views let you use PostgreSQL views with more granular access control over your data. While you can issue a GRANT statement to control whether a user can query a PostgreSQL view, a GRANT statement doesn't let you control the data that the view returns based on the user who is making the query.

To gain this level of control, use parameterized secure views. You can define parameters such as a user ID or region within the view. When your application queries the view, a user can provide values for these parameters, which customizes the query results. Using parameterized secure views lets you enforce "least privilege" access to help ensure that your users interact only with the data that is relevant and authorized to them.

This feature is in Preview.

Cloud SQL for SQL Server integration with Microsoft Entra ID (Preview) provides centralized identity and access management (IAM) for your databases using your existing Microsoft Entra ID tenant.

To help prevent out-of-memory (OOM) events, you can enable managed buffer pool for Cloud SQL for MySQL 8.0 and later instances. When you enable managed buffer pool, Cloud SQL reduces the value of the innodb_buffer_pool_size configuration and frees up memory when memory usage is high, and the instance is in danger of an OOM event. After memory usage stabilizes at a lower value, MySQL increases the value of innodb_buffer_pool_size incrementally to its original value.

To enable managed buffer pool, your Cloud SQL instance must use a maintenance version of [$MYSQL_VERSION].R20251004.01_07 or later. You can't enable managed buffer pool for instances that use a shared core or for instances that are running MySQL 5.6 or MySQL 5.7.

For more information, see Enable managed buffer pool. Support for managed buffer pool is in Preview.
