Ingestion time is distinct from event time, which is the time the data describes, and from processing
In practice, systems use ingestion time to order records, partition data for near-real-time queries, and handle
Common challenges include clock skew among distributed components, time zone handling, and ensuring consistent time sources.
In many pipelines, ingestion time complements event time and processing time. Analysts may compare the three
