为尽量减少对 Azure Databricks 用户的干扰，版本将定期进行部署。In order to minimize disruption to Azure Databricks users, releases are deployed on a regular cadence. 在部署过程中，Azure Databricks 服务可能会暂时中断。During a deployment, Azure Databricks services may be temporarily disrupted. 你该做好计划来应对这些计划性维护时段，避免在这些时段长时间运行的作业。You should plan for these scheduled maintenance windows and avoid long-running jobs during these times.
版本部署通常分为三个阶段，第 1 个阶段发生在星期二，第 2 阶段发生在星期四，第 3 阶段发生在下一个星期二。Release deployments typically occur in three stages, with Stage 1 occurring on a Tuesday, Stage 2 the following Thursday, and Stage 3 the following Tuesday.
版本部署计划在其所在区域的正常工作时间之外进行。Release deployments are scheduled outside of normal business hours for the region in which they occur.
部署阶段基于 Azure Databricks 工作区的区域。Your deployment stage is based on the region of your Azure Databricks workspace.
部署开始前，会有多种类型的通知，具体取决于部署模型。There are multiple types of notifications that appear before a deployment starts, depending on your deployment model.
以下各部分重点介绍了最常见的方法。The following sections highlight the most common methods.
状态页面自动通知Status Page automatic notification
如果你已订阅自动通知，则将在部署开始前收到一条警报，然后在部署结束时再收到一条警报。If you have subscribed to automatic notifications, you will receive an alert before a deployment begins, and then a second alert when the deployment has concluded. 这些警报可通过电子邮件或 Webhook 发送，具体取决于你配置的订阅类型。These can be via email or webhook, depending on the subscription type you have configured.
