All Implemented Interfaces:

Writeable

public class InvalidMappedTsField
extends EsField

Represents a field that has the same ES data type across all indices but conflicting time-series roles (e.g., DIMENSION in one index and METRIC in another).

Exists only during analysis and verification - it is not sent to data nodes. The analyzer converts this to an UnsupportedEsField-backed UnsupportedAttribute via mappingAsAttributes.

Unlike InvalidMappedField, which carries a typesToIndices map and can participate in union-type casts (e.g., field::double), a role conflict cannot be resolved by any cast, so this class is intentionally not a subclass of InvalidMappedField.

Crucially, this class is also not an UnsupportedEsField. The field-hierarchy walk in IndexResolver.mergedMappings propagates unsupported status to child fields when it encounters an UnsupportedEsField parent. By using a distinct type here, subfields with non-conflicting, supported types remain accessible.
