CDC for {astra-db} automatically captures changes in real time, de-duplicates the changes, and streams the clean set of changed data into {product} where it can be processed by client applications or sent to downstream systems.

{product} processes data changes via an {pulsar-reg} topic. By design, the Change Data Capture (CDC) component is simple, with a 1:1 correspondence between the table and a single {pulsar-short} topic.

Each externally exposed raw {product} metric is reported at a very low level, at each individual server instance (the `exported_instance` label) and each topic partition (the `topic` label). The same raw metrics could come from multiple server instances. From a {product} user's perspective, the direct monitoring of raw metrics is not really useful.
