This issue can also serve as the tracking issue for adding a true incremental-only startup mode to MongoDB-CDC. ## Proposed scope Add a startup option that begins consuming change stream events without taking an initial snapshot. ## Why this matters Today users who only want changes from "now onward" still hit full synchronization behavior in some paths. That makes MongoDB-CDC unsuitable for incremental-only onboarding and can create duplicate historical ingestion. ## Suggested acceptance criteria - `MongoDB-CDC` exposes a startup mode that skips the initial snapshot and starts from the latest change stream position. - The option is validated clearly in configuration parsing. - Restart and resume behavior is documented. - English and Chinese docs are updated with a minimal example. - Add a focused test path that proves snapshot is skipped and only new changes are consumed. ## Out of scope for the first delivery - Dynamic newly-added collection capture. - New metadata fields. - General CDC transform enhancements. -- This is an automated message from the Apache Git Service.
