示例

更改请求限制策略中的特定限制

更改 default 工作负荷组的请求限制策略中的特定限制，同时使以前定义的限制保持不变。

.alter-merge workload_group default ```
{
  "RequestLimitsPolicy": {
    "DataScope": {
      "IsRelaxable": false,
      "Value": "HotCache"
    },
    "MaxExecutionTime": {
      "IsRelaxable": false,
      "Value": "00:01:00"
    }
  }
} ```

输出

WorkloadGroupName WorkloadGroup
default {"RequestLimitsPolicy":{"DataScope":{"IsRelaxable":false,"Value":"HotCache"},"MaxMemoryPerQueryPerNode":{"IsRelaxable":true,"Value":8589699072},"MaxMemoryPerIterator":{"IsRelaxable":true,"Value":5368709120},"MaxFanoutThreadsPercentage":{"IsRelaxable":true,"Value":100},"MaxFanoutNodesPercentage":{"IsRelaxable":true,"Value":100},"MaxResultRecords":{"IsRelaxable":true,"Value":500000},"MaxResultBytes":{"IsRelaxable":true,"Value":67108864},"MaxExecutionTime":{"IsRelaxable":false,"Value":"00:01:00"}},"RequestRateLimitPolicies":[{"IsEnabled":true,"Scope":"WorkloadGroup","LimitKind":"ConcurrentRequests","Properties":{"MaxConcurrentRequests":100}}],"RequestRateLimitsEnforcementPolicy":{"QueriesEnforcementLevel":"QueryHead","CommandsEnforcementLevel":"Database"}}

更改请求速率限制策略

更改 default 工作负荷组的请求速率限制策略，同时使其所有其他策略保持不变。

.alter-merge workload_group default ```
{
  "RequestRateLimitPolicies": [
    {
      "IsEnabled": true,
      "Scope": "WorkloadGroup",
      "LimitKind": "ConcurrentRequests",
      "Properties": {
        "MaxConcurrentRequests": 100
      }
    }
  ]
} ```

输出

WorkloadGroupName WorkloadGroup
default {"RequestLimitsPolicy":{"DataScope":{"IsRelaxable":false,"Value":"HotCache"},"MaxMemoryPerQueryPerNode":{"IsRelaxable":true,"Value":8589699072},"MaxMemoryPerIterator":{"IsRelaxable":true,"Value":5368709120},"MaxFanoutThreadsPercentage":{"IsRelaxable":true,"Value":100},"MaxFanoutNodesPercentage":{"IsRelaxable":true,"Value":100},"MaxResultRecords":{"IsRelaxable":true,"Value":500000},"MaxResultBytes":{"IsRelaxable":true,"Value":67108864},"MaxExecutionTime":{"IsRelaxable":false,"Value":"00:01:00"}},"RequestRateLimitPolicies":[{"IsEnabled":true,"Scope":"WorkloadGroup","LimitKind":"ConcurrentRequests","Properties":{"MaxConcurrentRequests":100}}],"RequestRateLimitsEnforcementPolicy":{"QueriesEnforcementLevel":"QueryHead","CommandsEnforcementLevel":"Database"}}

更改请求队列策略

为 default 工作负荷组启用请求队列，同时使其请求限制策略和请求速率限制策略保持不变。

.alter-merge workload_group default ```
{
  "RequestQueuingPolicy": {
      "IsEnabled": true
  }
} ```

输出

WorkloadGroupName WorkloadGroup
default {"RequestLimitsPolicy":{"DataScope":{"IsRelaxable":false,"Value":"HotCache"},"MaxMemoryPerQueryPerNode":{"IsRelaxable":true,"Value":8589699072},"MaxMemoryPerIterator":{"IsRelaxable":true,"Value":5368709120},"MaxFanoutThreadsPercentage":{"IsRelaxable":true,"Value":100},"MaxFanoutNodesPercentage":{"IsRelaxable":true,"Value":100},"MaxResultRecords":{"IsRelaxable":true,"Value":500000},"MaxResultBytes":{"IsRelaxable":true,"Value":67108864},"MaxExecutionTime":{"IsRelaxable":false,"Value":"00:01:00"}},"RequestRateLimitPolicies":[{"IsEnabled":true,"Scope":"WorkloadGroup","LimitKind":"ConcurrentRequests","Properties":{"MaxConcurrentRequests":100}}],"RequestQueuingPolicy":{"IsEnabled":true},"RequestRateLimitsEnforcementPolicy":{"QueriesEnforcementLevel":\n"QueryHead","CommandsEnforcementLevel":"Database"}}

更改请求速率限制强制实施策略

为 default 工作负荷组启用请求速率限制强制实施策略，同时使其所有其他策略保持不变。

.alter-merge workload_group default ```
{
  "RequestRateLimitsEnforcementpolicy": {
      "QueriesEnforcementLevel": "QueryHead",
      "CommandsEnforcementLevel": "Cluster"
  }
} ```

输出

WorkloadGroupName WorkloadGroup
default {"RequestLimitsPolicy":{"DataScope":{"IsRelaxable":false,"Value":"HotCache"},"MaxMemoryPerQueryPerNode":{"IsRelaxable":true,"Value":8589699072},"MaxMemoryPerIterator":{"IsRelaxable":true,"Value":5368709120},"MaxFanoutThreadsPercentage":{"IsRelaxable":true,"Value":100},"MaxFanoutNodesPercentage":{"IsRelaxable":true,"Value":100},"MaxResultRecords":{"IsRelaxable":true,"Value":500000},"MaxResultBytes":{"IsRelaxable":true,"Value":67108864},"MaxExecutionTime":{"IsRelaxable":false,"Value":"00:01:00"}},"RequestRateLimitPolicies":[{"IsEnabled":true,"Scope":"WorkloadGroup","LimitKind":"ConcurrentRequests","Properties":{"MaxConcurrentRequests":100}}],"RequestQueuingPolicy":{"IsEnabled":true},"RequestRateLimitsEnforcementPolicy":{"QueriesEnforcementLevel":"QueryHead","CommandsEnforcementLevel":"Cluster"}}

更改查询一致性策略

为查询一致性模型指定适用的选项。

.alter-merge workload_group default ```
{
  "QueryConsistencyPolicy": {
     "QueryConsistency": {
        "IsRelaxable": true,
        "Value": "Weak"
     }
  }
} ```

输出

WorkloadGroupName WorkloadGroup
default {"RequestLimitsPolicy":{"DataScope":{"IsRelaxable":false,"Value":"HotCache"},"MaxMemoryPerQueryPerNode":{"IsRelaxable":true,"Value":8589699072},"MaxMemoryPerIterator":{"IsRelaxable":true,"Value":5368709120},"MaxFanoutThreadsPercentage":{"IsRelaxable":true,"Value":100},"MaxFanoutNodesPercentage":{"IsRelaxable":true,"Value":100},"MaxResultRecords":{"IsRelaxable":true,"Value":500000},"MaxResultBytes":{"IsRelaxable":true,"Value":67108864},"MaxExecutionTime":{"IsRelaxable":false,"Value":"00:01:00"}},"RequestRateLimitPolicies":[{"IsEnabled":true,"Scope":"WorkloadGroup","LimitKind":"ConcurrentRequests","Properties":{"MaxConcurrentRequests":100}}],"RequestQueuingPolicy":{"IsEnabled":true},"RequestRateLimitsEnforcementPolicy":{"QueriesEnforcementLevel":"QueryHead","CommandsEnforcementLevel":"Cluster"},"QueryConsistencyPolicy":{"QueryConsistency":{"IsRelaxable":true,"Value":"Weak"}}}
