An update to Spanner change streams provides two new data capture types for change records:
NEW_VALUESmode captures only new values in non-key columns, and no old values. Keys are always captured.NEW_ROWmode captures the full new row, including columns that are not included in updates. No old values are captured.
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.

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