PCLUSAPI_CLUSTER_ENUM类型定义指向此函数的指针。 语法 C++ 复制 DWORD ClusterEnum( [in] HCLUSENUM hEnum, [in] DWORD dwIndex, [out] LPDWORD lpdwType, [out] LPWSTR lpszName, [in, out] LPDWORD lpcchName ); 参数 [in] hEnum ClusterOpenEnum 函数返回的群集枚举句柄。 [in] dwIndex 用于...
1：每秒随机选取5个节点并找出最久没有通信的节点。num1~10：最近一次收受pong消息的时间 > cluster_node_timeout/2的节点。可以看出，参数cluster_node_timeout对ping消息发送的节点数量影响非常大。当带宽资源紧张时，可以适当调大该参数值，反之，过度调大该参数值会影响消息交换的频率，从而影响故障转移、槽信息...
put(2, bitmapDrawable); } return bitmapDrawable; } else if (clusterNum < 10) { Drawable bitmapDrawable = mBackDrawAbles.get(3); if (bitmapDrawable == null) { bitmapDrawable = new BitmapDrawable(null, drawCircle(radius, Color.argb(199, 217, 114, 0))); mBackDrawAbles.put(3, bit...
这样算出的数量可能不为整数,这里代码用了下面的方式处理: n = (numslots/source_tot_slots*s.slots.length) if i == 0 n = n.ceil else n = n.floor 这样的处理方式会带来最终分配的slot与请求迁移的slot数量不一致,这个BUG已经在github上提给作者,https://github.com/antirez/redis/issues/2990。 7...
一个节点除了会将自己负责处理的槽记录在 clusterNode 结构的 slots 属性和 numslots 属性之外,它还会将自己的 slots 数组通过消息发送给集群中的其他节点,以此来告知其他节点自己目前负责处理哪些槽。 当节点 A 通过消息从节点 B 那里接收到节点 B 的 slots 数组时, 节点 A 会在自己的 clusterState.nodes 字典...

clusterNode结构的slots属性和numslot属性记录了节点负责处理那些槽: struct clusterNode { //… unsignedchar slots[16384/8]; }; Slots属性是一个二进制位数组(bitarray),这个数组的长度为16384/8=2048个字节,共包含16384个二进制位。Master节点用bit来标识对于某个槽自己是否拥有。比如对于编号为1的槽,Master只...
