feat: support auto-generated primary keys with IDENTITY columns#503
Conversation
Adds support for auto-generated primary keys using IDENTITY columns. Standard primary key columns in Entity Framework are translated to `GENERATED BY DEFAULT AS IDENTITY (BIT_REVERSED_POSITIVE)` for Spanner. The methods added in SpannerModelBuilderExtensions can be used to configure the strategy for generating primary keys: `SpannerModelBuilderExtensions.DisableIdentityColumns()` disables the use of IDENTITY for primary keys. `SpannerModelBuilderExtensions.UseAutoIncrement()` configures the Entity Framework provider to generate `AUTO_INCREMENT` columns instead of a `GENERATED BY DEFAULT` clause. This can only be used if the database has a `default_sequence_kind` option set. The `SpannerModelExtensions.SetIdentityOptions` method can be used to manually configure the generation strategy. This can be used to set a custom sequence kind.
