Elasticsearch index settings:

• Index Settings Overview:

  • Index level settings can be set per-index.
  • Two types of settings:
  • Static: Set at index creation or on a closed index.
  • Dynamic: Changed on a live index using the update-index-settings API.

• Static Settings:

  • Set during index creation or on a closed index.
  • Can also be updated using the update-index-settings API with the reopen query parameter set to true.
  • Changing static settings on a closed index may lead to incorrect settings.

• Dynamic Settings:

  • Updated on an existing index without reindexing.
  • Provides flexibility for real-time adjustments.

Remember to test and validate settings based on your specific use case. 🚀🔍
