Debezium Blog
The engineering team at Shopify recently improved the Debezium MySQL connector so that it supports incremental snapshotting for databases without write access by the connector, which is required when pointing Debezium to read-only replicas. In addition, the Debezium MySQL connector now also allows schema changes during an incremental snapshot. This blog post explains the implementation details of those features.
One of the major improvements in Debezium starting in version 1.6 is support for incremental snapshots. In this blog post we are going to explain the motivation for this feature, we will do a deep dive into the implementation details, and we will also show a demo of it.
