Topology Notes

  • ·PostgreSQL logical replication slot feeds CDC connector (e.g. Debezium). Connector publishes per-table topics to Kafka.
  • ·Kafka topic partition count should be set at creation based on the anticipated peak consumer parallelism. Increasing partitions later breaks keyed message ordering.
  • ·Analytics consumers read from Kafka topics and write to a columnar analytics store (e.g. ClickHouse, BigQuery, Redshift). The analytics store is outside this scenario's scope.
  • ·Replication slot must be monitored. Set a WAL retention alert at 50% of available disk. A failing consumer that is not consuming will accumulate WAL indefinitely.
