Elasticsearch - Mappings and Data Types

Given this mapping for a field price as float:

{
  "properties": {
    "price": { "type": "float" }
  }
}

What will happen if you index a document with "price": "cheap"?

AElasticsearch will store the string 'cheap' as is without error

BElasticsearch will index the document but ignore the price field

CElasticsearch will convert 'cheap' to 0.0 automatically

DElasticsearch will reject the document with a mapping type conflict error

Step-by-Step Solution

Solution:

Step 1: Understand type enforcement in mappings
Elasticsearch enforces the data type defined in mappings. If a field is float, it expects a number.
Step 2: Analyze the input value
The value 'cheap' is a string, not a float, so Elasticsearch will raise a type conflict error when indexing.
Final Answer:
Elasticsearch will reject the document with a mapping type conflict error -> Option D
Quick Check:
Type mismatch causes error = Elasticsearch will reject the document with a mapping type conflict error [OK]

Quick Trick: Data must match mapping type or indexing fails [OK]
