	BeginGTX(ctx context.Context, globalRootContext context.Context) error

	CommitGTX(ctx context.Context, globalRootContext context.Context) error

	RollbackGTX(ctx context.Context, globalRootContext context.Context) error

	GetGTXID(ctx context.Context, globalRootContext context.Context) (string, error)

	// 重新包装为 seata/hptx 的context.RootContext
	// context.RootContext 如果后续使用了 context.WithValue,类型就是context.valueCtx 就会造成无法再类型断言为 context.RootContext
	// 所以DBDao里使用了 globalRootContext变量,区分业务的ctx和分布式事务的RootContext
	// NewRootContext(ctx context.Context) context.Context
