例如:我在同一个集群中有三个节点(" node1"," node2"" node3")。这些节点在配置文件hazelcast.xml中是相同的。我想要数据库" DB_1"仅放在第一个节点和第二个节点上。和数据库" DB_2"仅放在第二个和第三个节点上。
我修改了文件" default-distributed-db-config.json"在第一个节点和第二个节点上:
{
"autoDeploy": true,
"hotAlignment": false,
"executionMode": "undefined",
"readQuorum": 1,
"writeQuorum": 2,
"failureAvailableNodesLessQuorum": false,
"readYourWrites": true,
"servers": {
"*": "master"
},
"clusters": {
"internal": {
},
"index": {
},
"*": {
"servers": ["node1","node2"]
}
}
}
我修改了文件" default-distributed-db-config.json"在第三个节点上:
{
"autoDeploy": true,
"hotAlignment": false,
"executionMode": "undefined",
"readQuorum": 1,
"writeQuorum": 2,
"failureAvailableNodesLessQuorum": false,
"readYourWrites": true,
"servers": {
"*": "master"
},
"clusters": {
"internal": {
},
"index": {
},
"*": {
"servers": ["node3"]
}
}
}
我修改了文件" distributed-config.json"在数据库目录" DB_1"在第一个和第二个节点上。 我从中删除了所有内容:
<NEW_NODE>
并且到处写了第一个和第二个节点的唯一名称:
"*":{"@type":"d","@version":0,"servers":["node1","node2"]},"orole_node2":{"@type":"d","@version":0,"servers":["node2","node1"]},"e_node2":{"@type":"d","@version":0,"servers":["node2","node1"]},"ouser_node2":{"@type":"d","@version":0,"servers":["node2","node1"]},"oschedule_node2":{"@type":"d","@version":0,"servers":["node2","node1"]},"orids_node2":{"@type":"d","@version":0,"servers":["node2","node1"]},"v_node2":{"@type":"d","@version":0,"servers":["node2","node1"]},"ofunction_node2":{"@type":"d","@version":0,"servers":["node2","node1"]}}
但是,如果启动第三个节点,那么对于数据库&#34; DB_1&#34;也将在第三个节点中运行复制。

我认为不可能,同一群集的每个节点都必须与其他节点同步。
