Functions ¶
func TestRole ¶ added in v1.3.0
TestRole wraps GetRole in a test to verify if the role matches an expected role string. If there was any error in querying the supplied connection, the function returns false. Works with Redis >= 2.8.12. It's not goroutine safe, but if you call this method on pooled connections then you are OK.
Types ¶
type ConnPool ¶
type ConnPool struct {
// contains filtered or unexported fields
}
ConnPool redis连接池
func (*ConnPool) LuaScriptZset ¶ added in v1.2.0
func (rc *ConnPool) LuaScriptZset(script, key string, score int64, member string) (interface{}, error)
LuaScriptZset for SortedSet
func (*ConnPool) Zrangebyscore ¶ added in v1.2.4
Zrangebyscore for SortedSet all: -inf ~ +inf min ~ max min-max: (min ~ (max
func (*ConnPool) Zremrangebyrank ¶
Zremrangebyrank for SortedSet
func (*ConnPool) Zremrangebyscore ¶
Zremrangebyscore for SortedSet
type NoSentinelsAvailable ¶ added in v1.3.0
type NoSentinelsAvailable struct {
// contains filtered or unexported fields
}
NoSentinelsAvailable is returned when all sentinels in the list are exhausted (or none configured), and contains the last error returned by Dial (which may be nil)
func (NoSentinelsAvailable) Error ¶ added in v1.3.0
func (ns NoSentinelsAvailable) Error() string
type Sentinel ¶ added in v1.3.0
type Sentinel struct {
// Addrs is a slice with known Sentinel addresses.
Addrs []string
// MasterName is a name of Redis master Sentinel servers monitor.
MasterName string
// Dial is a user supplied function to connect to Sentinel on given address. This
// address will be chosen from Addrs slice.
// Note that as per the redis-sentinel client guidelines, a timeout is mandatory
// while connecting to Sentinels, and should not be set to 0.
Dial func(addr string) (redis.Conn, error)
// Pool is a user supplied function returning custom connection pool to Sentinel.
// This can be useful to tune options if you are not satisfied with what default
// Sentinel pool offers. See defaultPool() method for default pool implementation.
// In most cases you only need to provide Dial function and let this be nil.
Pool func(addr string) *redis.Pool
// contains filtered or unexported fields
}
Sentinel provides a way to add high availability (HA) to Redis Pool using preconfigured addresses of Sentinel servers and name of master which Sentinels monitor. It works with Redis >= 2.8.12 (mostly because of ROLE command that was introduced in that version, it's possible though to support old versions using INFO command).
func (*Sentinel) Discover ¶ added in v1.3.0
Discover allows to update list of known Sentinel addresses. From docs:
A client may update its internal list of Sentinel nodes following this procedure: 1) Obtain a list of other Sentinels for this master using the command SENTINEL sentinels <master-name>. 2) Add every ip:port pair not already existing in our list at the end of the list.
func (*Sentinel) MasterAddr ¶ added in v1.3.0
MasterAddr returns an address of current Redis master instance.
func (*Sentinel) SentinelAddrs ¶ added in v1.3.0
SentinelAddrs returns a slice of known Sentinel addresses Sentinel server aware of.
func (*Sentinel) SlaveAddrs ¶ added in v1.3.0
SlaveAddrs returns a slice with known slave addresses of current master instance.
