Record Class DeclaredSchemaResolver.Overlaid

java.lang.Object

org.elasticsearch.xpack.esql.datasources.DeclaredSchemaResolver.Overlaid
Enclosing class:
DeclaredSchemaResolver
public static record DeclaredSchemaResolver.Overlaid(List<Attribute> output, List<Attribute> fileSchema) extends Record
Result of a non-strict overlay: the user-facing output (declared columns renamed to their logical name and retyped, undeclared columns untouched) and the per-file fileSchema the reader resolves against the file. Both carry logical names — the operator's projection/column-mapping code stays in logical names and never sees the physical names; a path rename is applied at the reader-facing boundary via PhysicalNames (physical names then reach by-name readers; text readers read positionally). The two lists pair position-for-position.

      a hash code value for this object

    • equals

      public final boolean equals(Object o)
