Elasticsearch - Mappings and Data Types
You set dynamic mapping to false but still see new fields indexed. What is a likely cause?
ADynamic mapping false disables indexing, not mapping.
BDynamic mapping false only applies to text fields.
CElasticsearch caches old mappings ignoring new settings.
DThe new fields are defined in explicit mapping already.
Step-by-Step Solution
Solution:

  1. Step 1: Understand dynamic mapping false behavior

    Setting dynamic to false prevents new fields from being added automatically.

  2. Step 2: Reason why new fields appear

    If new fields are already defined explicitly, they will be indexed regardless of dynamic setting.

  3. Final Answer:

    The new fields are defined in explicit mapping already. -> Option D

  4. Quick Check:

    Explicit mapping overrides dynamic setting [OK]
Quick Trick: Explicit mapping fields index even if dynamic is false [OK]
Common Mistakes:
MISTAKES
  • Thinking dynamic false disables all indexing
  • Believing dynamic false applies only to text fields
  • Assuming Elasticsearch ignores mapping changes immediately
