func (*RedisStore) GetActiveTicketIDs 

func (s *RedisStore) GetActiveTicketIDs(ctx context.Context, limit int64) ([]string, error)

GetActiveTicketIDs may also retrieve tickets deleted by TTL. This is because the ticket index and Ticket data are stored in separate keys. The next `GetTickets` call will resolve this inconsistency.

func (*RedisStore) GetAssignment 

func (s *RedisStore) GetAssignment(ctx context.Context, ticketID string) (*pb.Assignment, error)

func (*RedisStore) GetTicket 

func (s *RedisStore) GetTicket(ctx context.Context, ticketID string) (*pb.Ticket, error)
