Class CompactInvalidMappedField

org.elasticsearch.xpack.esql.core.type.EsField

org.elasticsearch.xpack.esql.core.type.TypeConflictedField

org.elasticsearch.xpack.esql.core.type.CompactInvalidMappedField

All Implemented Interfaces:

Writeable

public final class CompactInvalidMappedField
extends TypeConflictedField

Memory-frugal counterpart to InvalidMappedField: stores at most 3 concrete index names per source type alongside an integer count of the names that were dropped. Together they let TypeConflictedField.errorMessage() reconstruct the same "and [N] other indices" rendering the full per-type list would have produced, without retaining the full list.

Modifier and Type	Method	Description
boolean	equals(Object obj)

static CompactInvalidMappedField	potentiallyUnmapped(String name, Map<DataType,Set<String>> typesToIndices, Map<Set<String>,Set<String>> indexDedupCache)
Set<DataType>	types()	Source data types observed for this field across all indices.

Method Details

mappedEverywhere

public static CompactInvalidMappedField mappedEverywhere(String name,
 Map<DataType,Set<String>> typesToIndices,
 Map<Set<String>,Set<String>> indexDedupCache)

potentiallyUnmapped

public static CompactInvalidMappedField potentiallyUnmapped(String name,
 Map<DataType,Set<String>> typesToIndices,
 Map<Set<String>,Set<String>> indexDedupCache)

writeContent

public void writeContent(StreamOutput out)
                  throws IOException

Description copied from class: EsField

This needs to be overridden by subclasses for specific serialization

Overrides:

writeContent in class EsField

Throws:

IOException

getWriteableName

public String getWriteableName(TransportVersion transportVersion)

Description copied from class: EsField

This needs to be overridden by subclasses for specific serialization

Overrides:

getWriteableName in class EsField

getTypesToIndices

public Map<String,Set<String>> getTypesToIndices()

Description copied from class: TypeConflictedField

Per-source-type indices in which the field appears with that type. Note that CompactInvalidMappedField caps each set and may include the "..." sentinel; callers that need a complete index list should use InvalidMappedField instead.

Specified by:

getTypesToIndices in class TypeConflictedField

isPotentiallyUnmapped

public boolean isPotentiallyUnmapped()

Description copied from class: TypeConflictedField

Whether the field is unmapped in at least one index, in which case it's treated as DataType.KEYWORD where it is unmapped.

Specified by:

isPotentiallyUnmapped in class TypeConflictedField

types

public Set<DataType> types()

Description copied from class: TypeConflictedField

Source data types observed for this field across all indices.

Specified by:

types in class TypeConflictedField

hashCode

public int hashCode()

Overrides:

hashCode in class EsField

equals

public boolean equals(Object obj)

Overrides:

equals in class EsField
