Databricks Light Databricks Light

Databricks Light 是開放原始碼 Apache Spark runtime 的 Databricks 封裝。Databricks Light is the Databricks packaging of the open source Apache Spark runtime. 其可針對不需要 Databricks Runtime 所提供進階效能、可靠性或自動調整優點的作業,提供執行階段選項。It provides a runtime option for jobs that don’t need the advanced performance, reliability, or autoscaling benefits provided by Databricks Runtime. 尤其是,Databricks Light 不支援:In particular, Databricks Light does not support:

  • Delta LakeDelta Lake
  • Autopilot 的功能,例如自動調整Autopilot features such as autoscaling
  • 高度並行、所有用途的群集Highly concurrent, all-purpose clusters
  • 筆記本、儀表板和協同作業功能Notebooks, dashboards, and collaboration features
  • 各種資料來源與 BI 工具的連接器Connectors to various data sources and BI tools

Databricks Light 是工作的執行時間環境, (或「自動化工作負載」 ) 。Databricks Light is a runtime environment for jobs (or “automated workloads”). 當您在 Databricks Light 叢集上執行作業時,它們會受限於較低的工作 Light 計算定價。When you run jobs on Databricks Light clusters, they are subject to lower Jobs Light Compute pricing. 只有當您建立或排程 JAR、Python 或 spark 提交 作業,並將叢集附加至該作業時,才可以選取 Databricks Light;您無法使用 Databricks Light 來執行筆記本工作或互動式工作負載。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 可以在相同的工作區中,與其他 Databricks 執行時間和定價層上執行的叢集搭配使用。Databricks Light can be used in the same workspace with clusters running on other Databricks runtimes and pricing tiers. 您不需要要求個別的工作區就能開始使用。You don’t need to request a separate workspace to get started.
