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"}}} |
