Databricks Light Databricks Light

Databricks Light 是开放源代码 Apache Spark 运行时的 Databricks 包。Databricks Light is the Databricks packaging of the open source Apache Spark runtime. 它为不需要 Databricks Runtime 所提供的高级性能、可靠性或自动缩放优势的作业提供运行时选项。It provides a runtime option for jobs that don’t need the advanced performance, reliability, or autoscaling benefits provided by Databricks Runtime. 特别是 Databricks Light 不支持:In particular, Databricks Light does not support:

  • Delta LakeDelta Lake
  • Autopilot 功能,如自动缩放Autopilot features such as autoscaling
  • 高度并发,通用群集Highly concurrent, all-purpose clusters
  • 笔记本、仪表板和协作功能Notebooks, dashboards, and collaboration features
  • 用于连接各种数据源和 BI 工具的连接器Connectors to various data sources and BI tools

Databricks Light 是作业(或“自动化工作负荷”)的运行时环境。Databricks Light is a runtime environment for jobs (or “automated workloads”). 在 Databricks Light 群集上运行作业时,它们会受到较低的作业轻量计算定价的限制。When you run jobs on Databricks Light clusters, they are subject to lower Jobs Light Compute pricing. 仅当创建或计划某个 JAR、Python 或 spark-submit 作业并将某个群集附加到该作业时,才可以选择 Databricks Light;不能使用 Databricks Light 运行笔记本作业或交互式工作负荷。You can select Databricks Light only when you create or schedule a JAR, Python, or spark-submit job and attach a cluster to that job; you cannot use Databricks Light to run notebook jobs or interactive workloads.

Databricks Light 可在与其他 Databricks 运行时和定价层上运行的群集相同的工作区中使用。Databricks Light can be used in the same workspace with clusters running on other Databricks runtimes and pricing tiers. 无需请求单独的工作区即可开始使用。You don’t need to request a separate workspace to get started.
