使用orientdb图模型时,是否存在全局配置以建立所有数据库写入以异步复制到其他节点?
答案 0 :(得分:1)
您需要的只是$ ORIENTDB_HOME / config / default-distributed-db-config.json文件。这是默认内容:
{
"replication": true,
"autoDeploy": true,
"hotAlignment": true,
"resyncEvery": 15,
"clusters": {
"internal": {
"replication": false
},
"index": {
"replication": false
},
"*": {
"replication": true,
"readQuorum": 1,
"writeQuorum": 2,
"failureAvailableNodesLessQuorum": false,
"readYourWrites": true,
"partitioning": {
"strategy": "round-robin",
"default": 0,
"partitions": [
[ "<NEW_NODE>" ]
]
}
}
}
}
默认情况下,writeQuorum为2.这意味着它在将ACK发送到客户端之前等待并检查来自至少2个节点的答案。您可以将其设置为1,因此所有写入都将是异步的。
