Term	Kind	Topic	What it is
Idempotent Sink	pattern	Exactly-Once Semantics	A destination where writing the same record twice has the same effect as writing it once, which is what makes end-to-end exactly-once achievable at all.
Replay Pipeline	pattern	Kappa vs Lambda	A single processing path that produces both live and historical results by re-running the same code over retained input, replacing the two-path Lambda arrangement.
Stream Enrichment	pattern	Streaming Joins	Attaching reference data to a stream by lookup against a materialised table rather than by joining two unbounded streams.
