func NewService

func NewService(runCtx context.Context, cfg Config) *Service

func (*Service) AcquireSession

func (svc *Service) AcquireSession(ctx context.Context) (*session.Session, func(), error)

func (*Service) Close

func (svc *Service) Close() error

func (*Service) Exec

func (svc *Service) Exec(
	ctx context.Context,
	query string,
	params map[string]*Ydb.TypedValue,
