What is the main purpose of shard allocation awareness in Elasticsearch?
ATo increase the number of shards in an index automatically
BTo compress shard data to save disk space
CTo speed up search queries by caching shards in memory
DTo spread shard copies across different physical locations for better fault tolerance
Step-by-Step Solution
Solution:

  1. Step 1: Understand shard allocation awareness concept

    Shard allocation awareness ensures that shard copies are placed on different physical locations like racks or machines.

  2. Step 2: Identify the benefit of spreading shards

    This spreading improves fault tolerance by preventing data loss if one location fails.

  3. Final Answer:

    To spread shard copies across different physical locations for better fault tolerance -> Option D

  4. Quick Check:

    Shard allocation awareness = spreading shards for fault tolerance [OK]
Quick Trick: Think about fault tolerance by spreading data copies [OK]
Common Mistakes:
MISTAKES
  • Confusing shard allocation awareness with shard count increase
  • Thinking it speeds up queries directly
  • Assuming it compresses data
