The external data catalog can be AWS Glue, the data catalog that comes with Amazon Athena, or your own Apache Hive metastore. Note. Athena works directly with the table metadata stored on the Glue Data Catalog while in the case Both are part of the AWS environment so it is quite natural to be a bit confused about which one you should use. Redshift Spectrum is a great choice if you wish to query your data residing over s3 and establish a relation between s3 and redshift cluster data. Redshift Spectrum and Athena both query data on S3 using virtual tables. Note: Because Redshift Spectrum and Athena both use the AWS Glue Data Catalog, we could use the Athena client to add the partition to the table. I have a table defined in Glue data catalog that I can query using Athena. You can also use AWS Glue’s fully-managed ETL capabilities to transform data or convert it into columnar formats to optimize cost and improve performance. マルチノード構成以外に、Redshift Spectrumを利用し、S3に直せるクエリを実行させることで可用性を高めることも可能です。 なお、この機能を利用するには、S3とRedshift Spectrumの間に、Amazon Athenaによって作成されたAWS Glueデータカタログか、Apache Hiveメタストアが必要です。 The process should take no more than 5 minutes. AWS Glue は未知のデータ(Dark Data)に対して、推測(Infer)して、AWS Glue Data Catalog にテーブルを登録する機能があり、これをクローラ(Crawler)として定義します。ガイド付きチュートリアルの中で、カラム名ありパーティション化されたS3オブジェクトをクロールする例をご紹介しています。 Redshift Spectrum is a great choice if you wish to query your data residing over s3 and establish a relation between s3 and redshift cluster data.

AWS GlueがGAになってから、Amazon Athena や AWS Glueの画面の先頭に、Upgrede to AWS Glue Data Catalog というメッセージがトップに表示されていると思います。本日、AWS Glue Data Catalogのアップグレードについて解説します。, Amazon Athena または Redshift Spectrum から AWS Glueによって作成されたテーブルとパーティションをクエリーするには、AWS Glue Data Catalogにアップグレードする必要があります。このアップグレード作業はウィザードを用いて、一度の実行するだけで済みます。, 尚、執筆時点では東京リージョン(ap-north-east-1)では、Glueがサービス開始していませんので、バージニア(us-east-1)、オハイオ(us-east-2)、オレゴン(us-west-2)のいずれかのリージョンでご利用ください。, Data Catalogとは、データベース、テーブル、パーティションに関する情報(メタデータ)を保存するものです。Amazon Athena や Amazon Redshift Spectrum ではこのメタデータを Apache Hive 互換のメタストアに保存します。よって、「Apache Hive メタストア」と呼ばれます。Apache Hive メタストアはHive、Presto、Spark、Pigで利用される Hadoopの世界では標準的なメタストアです。, AWS環境では、AWSアカウントかつリージョン毎にApache Hive メタストアが提供されています。アップグレード前でも、Amazon AthenaのテーブルをAmazon Redshift Spectrum、Amazon EMRから参照できるのはそのような理由です。, 今後、リージョン内のAmazon Athena、Amazon Redshift Spectrum、Amazon EMR、AWS Glueは、共通の Apache Hive メタストアにメタ情報を保存します。そうすることで、AWS GlueでETLしたデータをシームレスにAmazon Athena、Amazon Redshift Spectrum、Amazon EMRからクエリーできるようになります。, つまり、今回のアップグレードは、これまでAmazon Athena、Amazon Redshift Spectrum、Amazon EMR の用途に利用してきたApache Hive メタストアをAWS Glueでも利用できるように変換するという目的のアップグレードになります。, Data Catalog のアップグレードは、AWS Glueの画面に表示される以下のAthena Consoleというリンクをクリックすると、アップグレード用のウィザードが画面に遷移します。, そして、次の Upgrade to AWS Glue Data Catalog という画面の一番下のUpgradeボタンを押すと完了です。, Glueを利用したいだけの方は、読み飛ばして構いません。ウィザードが自動でアップグレードした変更点について、主にインフラエンジニア向けに解説します。アップグレードは、以下の3つのステップからなります。, このステップでは、ユーザーが管理しているIAMポリシーをアップデートします。ユーザーが管理しているIAMポリシーにAWS Glueへのアクセスを許可する権限を追加します。標示された変更前後のポリシーは以下のとおりです。実際には、管理ポリシー AmazonAthenaFullAccess が Version 1 から Version 3 の内容に更新されることのようです。, 次のポリシーは、Glue Data Catalogにアップグレードする権限を与えています。 管理ポリシーを使用する場合でも、このポリシーを追加する必要があります。 この操作が許可されているIAMユーザーは、すべてのユーザーに影響を与えるAWSアカウントのカタログ全体をアップグレードできます。, これまでのポリシーの更新を行ったら、アップグレードを開始できます。 ほんの数分しかかかりません。 問題が発生した場合やアップグレードをロールバックしたい場合は、サポートケースを開いてください。, これで AWS Glueが使える準備が整いました。更新前後の Aamzon Athenaのサンプルテーブル(sampledb.elb_logs)のテーブル定義を参照しても特に変更はありませんので、Aamzon Athena や Amazon Redshift Spectrum の動作には影響ありません。このData Cataogのアップデートがもたらす、AWS環境におけるビックデータ環境の今後についても理解できることを期待しています。, Deploying a Data Lake on AWS - AWS Online Tech Talks March 2017, Step 1a: Update user-managed IAM policies.
