FAQ
What does this tool tell you?
The CDC Reference covers Debezium, Postgres logical replication, replication slot monitoring, replication lag, CDC vs polling, and Kafka CDC architecture.
What affects the result most?
CDC: Change Data Capture — captures row-level changes (insert/update/delete) from database transaction log. Debezium: most popular open-source CDC connector — supports Postgres, MySQL, MongoDB, Oracle. Postgres CDC: uses logical replication slots — wal_level=logical required, replication slot monitoring critical.
How should I use the result?
Use this tool to orient quickly to the concepts, field names, or values you are about to look up in a full specification or vendor documentation. It summarizes the common cases; the authoritative source remains whichever standard or vendor doc defines the values themselves.
