Transaction Log
ⓘ
The database's transaction log that records all changes. In a real CDC system, this would be the database's native change log (e.g., MySQL binlog, PostgreSQL WAL).

No logs yet.

CDC Engine
ⓘ
The CDC engine that reads the binary log, transforms the data, and prepares it for the destination. This simulates real CDC tools like Debezium or Estuary.

No data extracted yet.

Destination
ⓘ
The target system that receives the transformed data. This could be a data warehouse, cache, or another database. Changes are applied based on the operation type (insert/update/delete).

No reduced data yet.
