Elasticsearch - Mappings and Data Types
Why do mappings define the structure of documents in Elasticsearch?

BBecause they store the actual data of the documents
CBecause they control the network settings of Elasticsearch nodes

Step-by-Step Solution

    Mappings tell Elasticsearch how to interpret each field in a document, like whether a field is text, number, date, etc.

  2. Step 2: Differentiate mappings from other settings

    Mappings do not store data or control network or permissions; they only define the structure and data types.

    Because they specify the data types and field properties for each document field -> Option A
