Term	Kind	Topic	What it is
CDC Initial Snapshot	concept	Change Data Capture	The consistent full copy taken when a CDC pipeline starts, before streaming begins — and the step that determines whether the target is correct.
Log-Based CDC	pattern	Change Data Capture	Capturing changes by reading the database's own write-ahead log, which sees every change with no load on the source and no application involvement.
Query-Based CDC Polling CDC, Timestamp-Based CDC	pattern	Change Data Capture	Detecting changes by repeatedly querying for rows modified since the last run — simple, universally available, and lossy in specific ways.
