I would like to introduce my small open-source project, called WAL-listener, available at https://github.com/ihippik/wal-listener This service is designed to keep you informed about any changes occurring in your PostgreSQL database. The core functionality of this service relies on leveraging the Write-Ahead Log (WAL) feature of PostgreSQL. The WAL plays a crucial role in maintaining data integrity within the database. For those interested in understanding WAL better, I recommend referring to the official documentation at https://www.postgresql.org/docs/current/wal-intro.html To receive notifications about database changes, wal-listener utilizes a message broker system. Initially, it supported only NATS as the message broker, but today, I am pleased to announce that Apache Kafka has been added as well, expanding its compatibility. I invite all members to explore and try out this extremely useful service. Your feedback and contributions are welcome!
