Term	Kind	Topic	What it is
CDC Pipeline Design	practice	CDC Pipeline Design	The concerns that turn log-based change capture from a demo into something that can be relied on — snapshots, ordering, schema change and replay.
Change Volume Ratio Update-to-Insert Ratio, Mutation Rate	metric	CDC Pipeline Design	The proportion of a change stream that is updates and deletes rather than inserts, which decides target storage design, merge cost and whether a table can be append-only.
Log-Based Ingestion	pattern	CDC Pipeline Design	Building the pipeline around a database's own change log — an initial snapshot followed by a continuous delta stream, with the two stitched together.
Snapshot-Stream Convergence Backfill Plus Change Stream, Initial Load Ordering	pattern	CDC Pipeline Design	Starting the change stream before taking the snapshot, so that changes occurring during the backfill are captured rather than silently lost.
