- Method Detail
  - hasBucketField
```
public static boolean hasBucketField(PartitionSpec spec)
```
    Check whether the spec contains a bucketed partition field.
    
    Parameters:
    
    spec - a partition spec
    
    Returns:
    
    true if the spec has field with a bucket transform
  - sortOrderFor
```
public static SortOrder sortOrderFor(PartitionSpec spec)
```
    Create a sort order that will group data for a partition spec.
    If the partition spec contains bucket columns, the sort order will also have a field to sort by a column that is bucketed in the spec. The column is selected by the highest number of buckets in the transform.
    
    Parameters:
    
    spec - a partition spec
    
    Returns:
    
    a sort order that will cluster data for the spec
  - partitionType
```
public static Types.StructType partitionType(Table table)
```
    Builds a common partition type for all specs in a table.
    Whenever a table has multiple specs, the partition type is a struct containing all columns that have ever been a part of any spec in the table.
    
    Parameters:
    
    table - a table with one or many specs
    
    Returns:
    
    the constructed common partition type
