CDC at Scale

Concepts: paCdc

What They Want to Hear 'Each source gets its own CDC connector, its own Kafka topic, and its own consumer. Failure isolation is the design principle: one source lagging does not block the others. I monitor three metrics per source: replication lag, event throughput, and error rate. When one falls behind, I diagnose independently: is it the WAL, the connector, or the consumer? Then I scale that one connector without touching the others.' This is the answer that shows you have operated CDC as a platform, not a single pipeline.
