The document provides an overview of real-time analytics using Spark Streaming. It discusses Spark Streaming's micro-batch approach of treating streaming data as a series of small batch jobs. This allows for low-latency analysis while integrating streaming and batch processing. The document also covers Spark Streaming's fault tolerance mechanisms and provides several examples of companies like Pea
ORC files were originally introduced in Hive, but have now migrated to an independent Apache project. This has sped up the development of ORC and simplified integrating ORC into other projects, such as Hadoop, Spark, Presto, and Nifi. There are also many new tools that are built on top of ORC, such as Hive’s ACID transactions and LLAP, which provides incredibly fast reads for your hot data. LLAP a
こんにちは。 Sparkについて調べてみよう企画第2段(?)です。 1回目はまずSparkとは何かの概要資料を確認してみました。 その先はRDDの構造を説明している論文と、後Spark Streamingというストリーム処理基盤の資料がありました。 とりあえず、そんなわけで(?)お手軽に概要がわかりそうなSpark Streamingの方を調べてみました。 まず見てみた資料は「Overview of Spark Streaming」(http://spark.incubator.apache.org/talks/strata_spark_streaming.pdf)です。 というわけで、読んだ結果をまとめてみます。 Spark Streamingとは何か? 大規模ストリーム処理フレームワーク ・100オーダーのノードにスケールする ・秒単位のレイテンシで処理を実行可能 ・Sparkのバッチ
