impl BoundPartitionSpec

pub fn builder(schema: impl Into<SchemaRef>) -> PartitionSpecBuilder

Create partition spec builder

pub fn unpartition_spec(schema: impl Into<SchemaRef>) -> Self

Get a new unpatitioned partition spec

pub fn spec_id(&self) -> i32

Spec id of the partition spec

pub fn fields(&self) -> &[PartitionField]

Fields of the partition spec

pub fn schema(&self) -> &Schema

The schema this partition spec is bound to

pub fn schema_ref(&self) -> &SchemaRef

The schema ref this partition spec is bound to

pub fn is_unpartitioned(&self) -> bool

Returns if the partition spec is unpartitioned.

A [PartitionSpec] is unpartitioned if it has no fields or all fields are Transform::Void transform.

pub fn into_unbound(self) -> UnboundPartitionSpec

Turn this partition spec into an unbound partition spec.

The field_id is retained as partition_id in the unbound partition spec.

pub fn into_schemaless(self) -> SchemalessPartitionSpec

Turn this partition spec into a preserved partition spec.

pub fn has_sequential_ids(&self) -> bool

Check if this partition spec has sequential partition ids. Sequential ids start from 1000 and increment by 1 for each field. This is required for spec version 1

pub fn highest_field_id(&self) -> Option<i32>

Get the highest field id in the partition spec. If the partition spec is unpartitioned, it returns the last unpartitioned last assigned id (999).

pub fn partition_type(&self) -> &StructType

Returns the partition type of this partition spec.

pub fn is_compatible_with_schemaless( &self, other: &SchemalessPartitionSpec, ) -> bool

Check if this partition spec is compatible with another partition spec.

Returns true if the partition spec is equal to the other spec with partition field ids ignored and spec_id ignored. The following must be identical:

The number of fields
Field order
Field names
Source column ids
Transforms
