Manually adding split points to your Spanner database is now generally available

## Feature Manually adding split points to your Spanner database is now generally available. Spanner automatically splits, or partitions, data in response to traffic changes to spread load across all available resources in an instance. For large, anticipated traffic changes, such as for a product launch, you can now pre-split the database with split boundaries that represent future traffic. This warmup can yield significant performance benefits for large scaling events. For more information about configuring split points for your database, see [Pre-splitting overview](https://cloud.google.com/spanner/docs/pre-splitting-overview).
