Presto、Spark SQLとHive on Tezの性能に関して、数万件から数十億件までのデータ上に、常用クエリパターンの実行スピードなどを検証してみた。 We conducted a benchmark test on mainstream big data sql engines including Presto, Spark SQL, Hive on Tez. We focused on the performance over medium data (from tens of GB to 1 TB) which is the major case used in most services. Read less
今日はPrestoとかAnsibleとかその辺の話を軽く書いてみようと思います。突っ込んだ話が出来るわけではないのであしからず。 僕のところの環境ではPrestoを使っていて、PrestoはDataNodeやNodeManagerと同居してます。主なユースケースはアドホッククエリの実行です。とあるレポートを作りたいってなったときにデータの中身をチェックするのに使います。従来だとこれがHiveだったのですが、HiveだとMapReduceになって遅いので（ローカルモードで済む場合もあるけど）、その点Prestoは早くていいです。ただこれは僕の環境がスモールデータだからっていうのもあって、圧縮済み数百GBのデータに対してselectかけるとかだとPrestoといえども遅くなると思います。あとなにげに良いのがPresto CLI経由だとカラム名が表示されるのでどのデータがどのカラムなのかすぐ分か
War of the Hadoop SQL engines. And the winner is …? You may have wondered why we were quiet over the last couple of weeks? Well, we locked ourselves into the basement and did some research and a couple of projects and PoCs on Hadoop, Big Data, and distributed processing frameworks in general. We were also looking at Clickstream data and Web Analytics solutions. Over the next couple of weeks we wil

Presto is an open source distributed SQL query engine, developed by Facebook. Presto was designed and written from the ground up for interactive analytics and approaches the speed of commercial data warehouses. Qubole started its Presto-as-a-Service program a few weeks ago to make it easily acces...
At a conference for developers at Facebook (s fb) headquarters on Thursday, engineers working for the social networking giant revealed that it’s using a new homemade query engine called Presto to do fast interactive analysis on its already enormous 250-petabyte-and-growing data warehouse. More than 850 Facebook employees use Presto every day, scanning 320 TB each day, engineer Martin Traverso said
