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.

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:

If you have tables with a large amount of unstructured data that can be represented as vector data, you can create a vector index using DDL statements and accelerate similarity searches and nearest neighbor queries using standard SQL using these functions without having to copy the data into a separate system. For more information, see Find approximate nearest neighbors to index and query vector embeddings in Spanner.

• Spanner now supports the use of Gemini models with GoogleSQL and PostgreSQL machine learning prediction functions.

To learn how to enable and activate Gemini in Databases, see Set up Gemini in Databases.

Spanner now supports the ML_PREDICT_ROW() function for PostgreSQL. You can use this function to generate predictions using SQL. To learn more about this function and how to use it, see Using Spanner Vertex AI integration functions.

You can now generate ML predictions using the Spanner emulator with GoogleSQL and PostgreSQL.

Spanner GoogleSQL now supports SAFE.ML.PREDICT(), which allows you to return a null instead of an error in your predictions.

You can generate and backfill vector embeddings for textual data (STRING or JSON) stored in Spanner using GoogleSQL partitioned DML and the Vertex AI textembedding-gecko model. For more information, see Generate vector embeddings for textual data in bulk using partitioned DML.

Spanner now supports several new PostgreSQL JSONB functions:

• spanner.jsonb_query_array()
• jsonb_build_array()
• jsonb_build_object()

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

For more information, see Supported PostgreSQL functions.

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.

The preview supports the Java, JDBC, Python, and Go Spanner clients as well as PostgreSQL drivers that connect through PGAdapter.

December 02, 2022
