Product Details
- 検索もAIも時系列も。専用DBを増やす前に、まずPostgres。アプリケーションの要件が増えるたびに、新しいデータベースを追加していませんか。全文検索には検索エンジン、生成AIにはベクトルデータベース、時系列データには時系列DB、位置情報には地理空間データベース。用途ごとに最適な製品を選べば高い性能や専門機能を得られる一方、システムが増えるほど、監視、バックアップ、権限管理、障害対応、データ連携、運用ノウハウもそれぞれ必要になります。そこで本書が提案するのが、「まずPostgresでできないかを考える」という選択肢です。PostgreSQL（Postgres）は、高速で信頼性の高いRDBMSであるだけでなく、長い歴史のなかで多彩な機能と拡張エコシステムを育ててきました。SQLによるトランザクション処理はもちろん、JSON、全文検索、ベクトル検索、時系列データ、地理空間データ、さらにはメッセージキューまで、1つのデータベースで扱える領域は想像以上に広がっています。本書では、まずPostgresの基本的な使い方、SQL、ウィンドウ関数やCTE、各種インデックスなど、日々のアプリケーション開発に欠かせない機能を整理します。そのうえで、全文検索とJSON、pgvectorを使った生成AI／ベクトル検索、TimescaleDBによる時系列処理、PostGISによる地理空間処理、pgmqを使ったメッセージキューなど、一般には専用システムが選ばれがちな用途を、実例とともに学んでいきます。B-tree、GIN、GiST、HNSWなど、用途に応じたインデックスの考え方やパフォーマンス改善についても扱います。もちろん、「何でもPostgresだけで済ませればよい」という本ではありません。大切なのは、新しい要件が出るたびに反射的に別のデータベースを導入するのではなく、Postgresで実現できる範囲と限界を知ったうえで、本当に必要な技術を選ぶことです。データベース構成をシンプルに保ちたいアプリケーション開発者、ソフトウェアエンジニア、アーキテクトに向けて、Postgresの「守備範囲」を現代の開発視点から捉え直す実践書です。※この商品は固定レイアウト型の電子書籍です。※この商品はタブレットなど大きいディスプレイを備えた端末で読むことに適しています。また、文字列のハイライトや検索、辞書の参照、引用などの機能が使用できません。※お使いの端末で無料サンプルをお試しいただいた上でのご購入をお願いいたします。
