はじめに こんにちは、データインテグレーション部の近藤です。 今回は、RDSにおいて、PostgreSQLの設定のwal_levelをreplicaからlogicalに変更することにより、PostgreSQLのトランザクションログ(WAL)へChange Data Capture(以下、CDC)に必要を内容を出力させる設定方法をご紹介します。 wal_levelを設定することになった経緯 データベース移行サービスであるAmazon Database Migration Service(以下、DMS)には、継続的なレプリケーション機能(差分更新)の機能があります。この動作テストを行おうと、ソースDBをRDSのPostgreSQL、ターゲットDBをS3としてタスクを作り動かしました。ソースDBのPostgreSQLにデータを逐次INSERTし、それに伴いターゲットDBであるS3にオブジェクトが

PostgreSQL is an open source relational database. Kafka is an open source log-based messaging system. Because both systems are powerful and flexible, they’re devouring whole categories of infrastructure. And they’re even better together. In this talk, you’ll learn about commit logs and how that fundamental data structure underlies both PostgreSQL and Kafka. We’ll use that basis to understand what
Summary: Confluent is starting to explore the integration of databases with event streams. As part of the first step in this exploration, Martin Kleppmann has made a new open source tool called Bottled Water. It lets you transform your PostgreSQL database into a stream of structured Kafka events. This is tremendously useful for data integration. Writing to a database is easy, but getting the data
Debezium is an open source distributed platform for change data capture. Start it up, point it at your databases, and your apps can start responding to all of the inserts, updates, and deletes that other apps commit to your databases. Debezium is durable and fast, so your apps can respond quickly and never miss an event, even when things go wrong. Try our tutorial Stream changes from your database
In this blog, we’ll walk through an example of using Kafka Connect to consume writes to PostgreSQL, and automatically send them to Redshift. With this configuration, your analytics database can be updated with the latest production data in real-time, without any manual ETL jobs. Interested in transitioning to a career in data engineering?

At all times, PostgreSQL maintains a write ahead log (WAL) in the pg_wal/ subdirectory of the cluster's data directory. The log records every change made to the database's data files. This log exists primarily for crash-safety purposes: if the system crashes, the database can be restored to consistency by “replaying” the log entries made since the last checkpoint. However, the existence of the log
