在 Azure 数据资源管理器中管理纵向扩展(缩减)群集以适应不断变化的需求Manage cluster vertical scaling (scale up) in Azure Data Explorer to accommodate changing demand

调整好群集的大小对于 Azure 数据资源管理器的性能至关重要。Sizing a cluster appropriately is critical to the performance of Azure Data Explorer. 静态群集大小可能导致利用不充分或利用过度,二者都不理想。A static cluster size can lead to under-utilization or over-utilization, neither of which is ideal.

由于无法绝对准确地预测群集的需求,更好的方法是对群集进行缩放,根据不断变化的需求添加或删除容量和 CPU 资源。Since demand on a cluster can’t be predicted with absolute accuracy, a better approach is to scale a cluster, adding and removing capacity and CPU resources with changing demand.

有两个工作流可用于缩放 Azure 数据资源管理器群集:There are two workflows for scaling an Azure Data Explorer cluster:

  • 水平缩放,也称为缩减和横向扩展。Horizontal scaling, also called scaling in and out.
  • 垂直缩放,也称为纵向扩展和缩减。Vertical scaling, also called scaling up and down.

本文介绍垂直缩放工作流:This article explains the vertical scaling workflow:

配置垂直缩放Configure vertical scaling

  1. 在 Azure 门户中,转到 Azure 数据资源管理器群集资源。In the Azure portal, go to your Azure Data Explorer cluster resource. 在“设置”下选择“纵向扩展”。 Under Settings, select Scale up.

  2. 在“纵向扩展” 窗口中,你将看到群集的可用 SKU 列表。In the Scale up window, you will see a list of available SKUs for your cluster. 例如,在下图中,只有四个 SKU 可用。For example, in the following figure, only four SKUs are available.

    纵向扩展

    SKU 被禁用是因为它们是当前的 SKU,或者在群集所在区域不可用。The SKUs are disabled because they're the current SKU, or they aren't available in the region where the cluster is located.

  3. 若要更改 SKU,请选择一个新 SKU,然后单击“选择” 。To change your SKU, select a new SKU and click Select.

备注

  • 垂直缩放过程可能需要几分钟时间,在此期间群集将被挂起。The vertical scaling process can take a few minutes, and during that time your cluster will be suspended.
  • 缩减可能会损害群集性能。Scaling down can harm your cluster performance.
  • 价格是对群集的虚拟机和 Azure 数据资源管理器服务成本的估算值。The price is an estimate of the cluster's virtual machines and Azure Data Explorer service costs. 不包括其他成本。Other costs are not included. 有关估算值,请参阅 Azure 数据资源管理器成本估算器页;有关完整定价信息,请参阅 Azure 数据资源管理器定价页See Azure Data Explorer cost estimator page for an estimate and the Azure Data Explorer pricing page for full pricing information.

现在已为 Azure 数据资源管理器群集配置了垂直缩放。You've now configured vertical scaling for your Azure Data Explorer cluster. 添加另一个水平缩放规则。Add another rule for a horizontal scaling. 如果在解决群集缩放问题时需要帮助,请在 Azure 门户中提交支持请求If you need assistance with cluster-scaling issues, open a support request in the Azure portal.
