Default backup schedules are now available and automatically enabled for all new instances. You can enable or disable default backup schedules in an instance when creating the instance or by editing the instance later. You can also enable default backup schedules for new databases in existing instances. You can edit or delete the default backup schedule once it's created.

When enabled, Spanner creates a default backup schedule for every new database created in the instance. The default backup schedule creates a full backup every 24 hours. These backups have a retention period of 7 days.

For more information, see Default backup schedules.

Spanner now lets you create incremental backups through a backup schedule. You can specify when and how often backups are created, and how long they're retained.

An incremental backup contains only the data that has changed since the previous backup. Incremental backups typically consume less storage, and can help reduce your storage costs.

Incremental backups are available on the Enterprise and Enterprise Plus editions.

For more information about incremental backups, see Backups overview.

Spanner is now available on Database Center in Preview. You can track your Spanner resources in the fleet inventory section and the resource table in the Database Center. You can also use Database Center to monitor the following health issues for your Spanner resources:

• jsonb_build_array()
• jsonb_build_object()

The PostgreSQL CONCAT() function also supports more than 4 arguments.

For more information, see Supported PostgreSQL functions.

Note that existing change streams remain set to OLD_AND_NEW_VALUES.

December 06, 2022

We identified an issue in how we calculate the Total Database Storage metric in multi-regional Spanner instances. This metric is used to calculate the charges for Spanner database storage.

Database storage is currently incorrectly reported lower than it actually is in multi-regional configurations, resulting in undercharging for database storage. We communicated a Service Announcement in October and started rolling out this change to pricing on December 1, 2022. Depending on your configuration, your Total Database Storage could increase by up to 25%.

For the majority of impacted customers, the impact on your total bill will be less than 0.5%. For those affected, you will notice an increase in database storage charges that reflect this corrected metric.

We waived the under-billed amount for all past billing cycles. Please note that this issue only affects multi-region configurations of Spanner. It does not affect regional configurations of Spanner. Additionally, the Total Backup Storage metric is not affected by this issue, and has always been reported correctly.

For more information, see Database storage prices.

December 05, 2022

New SQL syntax, RETURNING in the PostgreSQL dialect and THEN RETURN in Google Standard SQL, selects and returns data from rows that were just updated as part of a DML statement. This is especially useful for getting values from default or generated columns and can reduce latency over equivalent multi-statement transactions. The preview supports the Java, JDBC, Python, and Go Spanner clients as well as PostgreSQL drivers that connect through PGAdapter.

December 02, 2022

The number of concurrent database restore operations per instance that Cloud Spanner supports has increased from five to ten. For more information, see Backup and restore limits.

November 15, 2022

Time to live (TTL) is now supported in PostgreSQL-dialect databases. With TTL, you can reduce storage costs, improve query performance, and simplify data retention by automatically removing unneeded data based on user-defined policies.

Added support for the JSONB data type in the Cloud Spanner PostgreSQL dialect. For more information, see Work with JSONB data.

November 08, 2022

Cloud Spanner now supports cross-region and cross-project backup use cases. You can copy a backup of your database from one instance to another instance in a different region or project to provide additional data protection and compliance capabilities.
