Streaming, CDC, and Near-Real-Time
摘要
Near-real-time on Snowflake is less about a single feature and more about how you land deltas quickly, track change safely, and publish stable views without noisy rewrites. Two ingestion lanes do the heavy lifting—Snowpipe (files) and Snowpipe Streaming (rows)—while CDC tools supply the change feed. Inside Snowflake, Streams expose those changes as first-class tables, and Tasks move them into dimensions and facts with idempotent merges. When the pieces are aligned, dashboards feel fresh, backfills are routine, and recovery is just a re-run.
