Types

type Store

type Store struct {
}

Store is the storage with redis, all transaction information will bachend with redis

func (*Store) ChangeGlobalStatus

func (s *Store) ChangeGlobalStatus(global *storage.TransGlobalStore, newStatus string, updates []string, finished bool)

ChangeGlobalStatus changes global trans status

func (*Store) CreateKV

func (s *Store) CreateKV(cat, key, value string) error

CreateKV creates key-value pair

func (*Store) DeleteKV

func (s *Store) DeleteKV(cat, key string) error

DeleteKV deletes key-value pair

func (*Store) FindBranches

func (s *Store) FindBranches(gid string) []storage.TransBranchStore

FindBranches finds Branch data by gid

func (*Store) FindKV

func (s *Store) FindKV(cat, key string) []storage.KVStore
