org.elasticsearch.xpack.esql.datasources.PartitionMetadata
public record PartitionMetadata(Map<String,DataType> partitionColumns, Map<StoragePath,Map<String,Object>> filePartitionValues) extends Record
Holds partition information detected from file paths. Maps partition column names to their inferred types, and each file path to its extracted partition key-value pairs. Both maps preserve insertion order so that partition columns appear in the same order they are declared in the path.

      the value of the partitionColumns record component

    • filePartitionValues

      public Map<StoragePath,Map<String,Object>> filePartitionValues()
      Returns the value of the filePartitionValues record component.
      Returns:
      the value of the filePartitionValues record component
