Apache Spark 是大規模資料分析的分散式處理架構。 您可以在下列服務中使用 Microsoft Azure 上的 Spark: Microsoft Fabric Azure Databricks Spark 可用來在多個叢集節點之間平行執行程式碼 (通常以 Python、Scala 或 JAVA 撰寫),這讓其可以有效率地處理非常大量的資料。 Spark 可用於批次處理和串流處理。
Structured Streaming (结构化流)是一种基于 Spark SQL 引擎构建的可扩展且容错的 stream processing engine (流处理引擎)。您可以以静态数据表示批量计算的方式来表达 streaming computation (流式计算)。 Spark SQL 引擎将随着 streaming data 持续到达而增量地持续地运行,并更新最终结果。您可以使用 Scala , Java ...
