A code snippet showing how to open a Parquet file with Hardwood and read its records via the row reader API.

A Grafana dashboard showing several metrics of the replication slots used by several Debezium connector instances: activity status, WAL retained, replication lag, etc.

A visual which shows a data pipeline from a Postgres database. An application writes to the "Authors" table in that database. Debezium captures the changes to that table from the Postgres WAL and writes them to Kafka. Apache Flink processes the data change events from this topic, enriches them with any missing TOAST column values using a state store, and writes them into another Kafka topic.
