How can the Outbox pattern be combined with Change Data Capture (CDC) to improve event reliability?

ACDC reads database transaction logs to publish events without modifying application code

BCDC deletes events from Outbox after publishing

CCDC replaces the need for an Outbox table entirely

DCDC caches events on client devices for offline use

Step-by-Step Solution

Solution:

Step 1: Understand CDC role
CDC captures changes from database logs, enabling event publishing without app code changes.
Step 2: Identify how CDC complements Outbox
CDC reads Outbox inserts and publishes events reliably, decoupling publishing logic.
Final Answer:
CDC reads database transaction logs to publish events without modifying application code -> Option A
Quick Check:
CDC + Outbox = decoupled event publishing [OK]

Quick Trick: CDC reads DB logs to publish events independently [OK]
