Step-by-Step Solution
Solution:
Step 1: Understand effect of large segment size
Larger log segments mean more data per file, causing longer flush and recovery times.Step 2: Compare with other options
More frequent rollovers happen with smaller segments, network latency is unrelated, and disk space usage usually increases with larger segments.Final Answer:
Longer disk flush times and slower recovery -> Option CQuick Check:
Large log.segment.bytes = longer flush and recovery [OK]
Quick Trick: Big segments slow disk flush and recovery [OK]
Common Mistakes:
MISTAKES- Thinking bigger segments cause more rollovers
- Confusing disk I/O with network latency
- Assuming disk space decreases with bigger segments
