Microservices - Event-Driven Architecture
During event replay, a microservice crashes due to missing event data. What is the best debugging step?
ARestart the microservice repeatedly
BVerify event log completeness and integrity
CIncrease memory allocation without checking logs
DDisable event replay temporarily
Step-by-Step Solution
Solution:

  1. Step 1: Identify cause of crash

    Missing event data suggests incomplete or corrupted event log.

  2. Step 2: Choose debugging action

    Verifying event log integrity helps find missing or corrupted events. Restarting or increasing memory ignores root cause. Disabling replay avoids problem but does not fix it.

  3. Final Answer:

    Verify event log completeness and integrity -> Option B

  4. Quick Check:

    Check event log health first [OK]
Quick Trick: Check event log integrity before other fixes [OK]
Common Mistakes:
MISTAKES
  • Restarting without checking logs
  • Ignoring missing data cause
  • Disabling replay instead of debugging
