Can Debezium Lose Events?

This technical article addresses a key question from the data engineering community: Can Debezium lose database change events? It explains Debezium's at-least-once delivery guarantee and how event loss is considered a critical bug. The discussion details operational scenarios where events could be missed, such as transaction log retention limits in MySQL and SQL Server, and contrasts this with PostgreSQL's replication slot mechanism and its disk space implications.
