Inspect deduplication keys

Compare how three key strategies represent the same synthetic event.

How to use this explorer

Move between stages with the arrows or the numbered stage list. Each stage shows the input it receives on the left and the output it produces on the right, with the lines that changed marked. The configuration that makes the change sits below the comparison, and the final stage shows the complete pipeline.

The 5 stages in order

  1. Original Events
    Multiple events arrive with potential duplicates from network retries, load balancer failovers, and eventual consistency delays.
  2. Hash-Based Deduplication
    Generate SHA-256 hash of entire event content and cache it. Identical events (same JSON structure) are detected and filtered.
  3. Fingerprint-Based Deduplication
    Build a comparison key from the selected user ID, email, and action-type fields.
  4. ID-Based Deduplication
    Use a source-supplied event ID as the cache key when its producer contract defines uniqueness.
  5. External Cache Configuration
    A review configuration sketches Redis, local fallback, metrics, and error-handling dependencies.
