连接池 node_address -> connection_pool
Functions ¶
func DestroyConnPools ¶
func DestroyConnPools()
func Push2GraphSendQueue ¶
将数据 打入 某个Graph的发送缓存队列, 具体是哪一个Graph 由一致性哈希 决定 如果正在数据迁移, 数据除了打到原有配置上 还要向新的配置上打一份(新老重叠时要去重,防止将一条数据向一台Graph上打两次)
func Push2JudgeSendQueue ¶
将数据 打入 某个Judge的发送缓存队列, 具体是哪一个Judge 由一致性哈希 决定
Types ¶
type ConsistentHashNodeRing ¶
type ConsistentHashNodeRing struct {
// contains filtered or unexported fields
}

var ( JudgeNodeRing *ConsistentHashNodeRing GraphNodeRing *ConsistentHashNodeRing GraphMigratingNodeRing *ConsistentHashNodeRing )
服务节点的一致性哈希环 pk -> node
func (*ConsistentHashNodeRing) GetNode ¶
func (this *ConsistentHashNodeRing) GetNode(pk string) (string, error)
根据pk,获取node节点. chash(pk) -> node
func (*ConsistentHashNodeRing) SetNodes ¶
func (this *ConsistentHashNodeRing) SetNodes(nodes []string)
func (*ConsistentHashNodeRing) SetNumberOfReplicas ¶
func (this *ConsistentHashNodeRing) SetNumberOfReplicas(num int)
