Elasticsearch - Index Management

You wrote this JSON to create an index:

{ "settings": { "number_of_shards": 1, "number_of_replicas": 1 }, "mapping": { "properties": { "name": { "type": "keyword" } } } }

Why are the mappings not applied?

ABecause "type" keyword is invalid

BBecause "mapping" should be "mappings"

CBecause "number_of_replicas" cannot be 1

DBecause "properties" is missing

Step-by-Step Solution

Solution:

Step 1: Check the JSON keys
The key "mapping" is incorrect; it should be "mappings" in Elasticsearch.
Step 2: Understand impact of wrong key
Using "mapping" causes Elasticsearch to ignore the mappings section.
Final Answer:
Because "mapping" should be "mappings" -> Option B
Quick Check:
Correct key is "mappings" [OK]

Quick Trick: Use "mappings" not "mapping" for field definitions [OK]
