Why does Elasticsearch recommend tuning the bulk request size rather than always using the largest possible size?
hard🧠 Conceptual Q10 of Q15
Step-by-Step Solution
Solution:
Step 1: Understand impact of bulk request size
Very large bulk requests consume more memory and CPU, potentially slowing indexing.Step 2: Recognize why tuning is needed
Optimal bulk size balances throughput and resource usage to avoid pressure.Final Answer:
Too large bulk requests can cause memory pressure and slow down indexing -> Option CQuick Check:
Bulk size tuning avoids memory pressure [OK]
Quick Trick: Tune bulk size to balance speed and resource use [OK]
Common Mistakes:
MISTAKES- Believing large bulk requests cause data loss
- Thinking bulk size has no performance impact
- Assuming small bulk requests cause crashes
