Cloud SQL for MySQL now lets you have more control over the number of results
that are returned when you perform an ANN vector search with filters.
You can use iterative filtering when the selective filters of the
WHERE clause in your ANN search query produce fewer results
than the number of results specified in your LIMIT clause.
To enable iterative filtering for your ANN search query, set the
cloudsql_vector_iterative_filtering flag to ON.
You can set the flag at a session or global level.
To enable and use iterative filtering for your ANN search query, you must have
[MYSQL_$VERSION].R20251004.01_07
or later installed on your MySQL instance.
For more information, see Search approximate nearest neighbors (ANN).

Cloud SQL now supports the
automatic minor version upgrade
for Cloud SQL for MySQL 8.0.35 or later instances.
If your Cloud SQL for MySQL instance is running MySQL 8.0.35 or later, but
you didn't select a specific minor version when you created the instance (databaseVersion=MYSQL_8_0),
then your MySQL instance is upgraded automatically to the default minor version
of Cloud SQL for MySQL 8.0 during its regular scheduled maintenance update.
All eligible Cloud SQL for MySQL instances receive the first automatic
minor version upgrade during the rollout of MYSQL_8_0_[N].R20251004.01_07.

Cloud SQL has enhanced the optimized writes feature, which includes an improved crash recovery algorithm to reduce crash recovery time and utilizes unused disk I/O throughput adaptively to accelerate buffer pool warm-up. The optimized writes feature provides a set of write performance improvements that adjust MySQL configurations dynamically based on workload demand and underlying infrastructure.
By default these improvements are enabled for all new Cloud SQL Enterprise Plus edition instances that you create or that you upgrade to from Cloud SQL Enterprise edition.
For more information about optimized writes, see Configure database flags.
October 17, 2025
Cloud SQL Enterprise edition now supports a new machine series called the N4 machine series. This machine series provides balanced price-to-performance and uses the Hyperdisk Balanced storage.

For more information about the N4 machine series and its availability, see Machine series overview.
The C4A machine series is now generally available (GA).
The C4A machine series is supported for Cloud SQL Enterprise Plus edition instances, and provides optimized price-performance and delivers predictable high performance for high demand Cloud SQL workloads. It uses the Hyperdisk Balanced storage.
For more information about the C4A machine series and its availability, see Machine series overview.

Cloud SQL Second Generation MySQL instances have a new high availability (HA) configuration. The new HA configuration, based on Google's Regional Disks, eliminates replication lag and, combined with automatic failover, provides isolation from many types of infrastructure, hardware, and software failures. Regional disks also ensure that all previously committed database transactions are persisted and available after failover, right up to the time of the failure.
The new high availability configuration is the default. You can continue to use the API to create instances with the legacy high availability configuration (using failover replicas) until the upgrade of existing instances occurs in early 2020. To learn how high availability now works for Second Generation MySQL instances, see the Overview of the high availability configuration. To enable high availability on existing instances, or to create new instances with high availability, see Enabling and disabling high availability on an instance.
