定义请求限制策略

创建 MyWorkloadGroup 工作负荷组并完整定义其请求限制策略：

.create-or-alter workload_group MyWorkloadGroup ```
{
  "RequestLimitsPolicy": {
    "DataScope": {
      "IsRelaxable": true,
      "Value": "HotCache"
    },
    "MaxMemoryPerQueryPerNode": {
      "IsRelaxable": false,
      "Value": 6442450944
    },
    "MaxMemoryPerIterator": {
      "IsRelaxable": false,
      "Value": 5368709120
    },
    "MaxFanoutThreadsPercentage": {
      "IsRelaxable": true,
      "Value": 100
    },
    "MaxFanoutNodesPercentage": {
      "IsRelaxable": true,
      "Value": 100
    },
    "MaxResultRecords": {
      "IsRelaxable": true,

    "QueryResultsCacheMaxAge": {
      "IsRelaxable": true,
      "Value": "00:05:00"
    }
  }
} ```
