Functions

func ToLevelDBURI

func ToLevelDBURI(connection string) *url.URL

ToLevelDBURI converts old style connections to a LevelDBURI

A LevelDBURI matches the pattern:

leveldb://path[?[option=value]*]

We have previously just provided the path but this prevent other options

func ToRedisURI

func ToRedisURI(connection string) *url.URL

ToRedisURI converts old style connections to a RedisURI

A RedisURI matches the pattern:

redis://[username:password@]host[:port][/database][?[option=value]*] rediss://[username:password@]host[:port][/database][?[option=value]*] redis+socket://[username:password@]path[/database][?[option=value]*] redis+sentinel://[password@]host1 [: port1][, host2 [:port2]][, hostN [:portN]][/ database][?[option=value]*] redis+cluster://[password@]host1 [: port1][, host2 [:port2]][, hostN [:portN]][/ database][?[option=value]*]

We have previously used a URI like: addrs=127.0.0.1:6379 db=0 network=tcp,addr=127.0.0.1:6379,password=macaron,db=0,pool_size=100,idle_timeout=180

We need to convert this old style to the new style

Types

type Manager

type Manager struct {
	RedisConnections   map[string]*redisClientHolder
	LevelDBConnections map[string]*levelDBHolder
	// contains filtered or unexported fields
}

Manager is the nosql connection manager

func GetManager

func GetManager() *Manager

GetManager returns a Manager and initializes one as singleton is there's none yet

func (*Manager) CloseLevelDB

func (m *Manager) CloseLevelDB(connection string) error

CloseLevelDB closes a levelDB

func (*Manager) CloseRedisClient

func (m *Manager) CloseRedisClient(connection string) error

CloseRedisClient closes a redis client

func (*Manager) GetLevelDB

func (m *Manager) GetLevelDB(connection string) (db *leveldb.DB, err error)

GetLevelDB gets a levelDB for a particular connection

func (*Manager) GetRedisClient

func (m *Manager) GetRedisClient(connection string) (client redis.UniversalClient)

GetRedisClient gets a redis client for a particular connection
