Workarounds

  1. 90% success Use flattened field type for dynamic key-value data
  2. 88% success Review data model: normalize nested objects, use keyword for sparse fields

  1. Set index.mapping.total_fields.limit to unlimited 82% fail

    Memory and performance degradation

  2. Disable dynamic mapping globally 75% fail
