Struct RecordBatchPartitionSplitter Copy item path

impl RecordBatchPartitionSplitter

pub fn try_new( iceberg_schema: SchemaRef, partition_spec: PartitionSpecRef, calculator: Option<PartitionValueCalculator>, ) -> Result<Self>

Create a new RecordBatchPartitionSplitter.

§Arguments

iceberg_schema - The Iceberg schema reference
partition_spec - The partition specification reference
calculator - Optional calculator for computing partition values from source columns.
- Some(calculator): Compute partition values from source columns using transforms
- None: Expect a pre-computed _partition column in the input batch

§Returns

Returns a new RecordBatchPartitionSplitter instance or an error if initialization fails.

pub fn try_new_with_computed_values( iceberg_schema: SchemaRef, partition_spec: PartitionSpecRef, ) -> Result<Self>

Create a new RecordBatchPartitionSplitter with computed partition values.

This is a convenience method that creates a calculator and initializes the splitter to compute partition values from source columns.

§Arguments

iceberg_schema - The Iceberg schema reference
partition_spec - The partition specification reference

§Returns

Returns a new RecordBatchPartitionSplitter instance or an error if initialization fails.

pub fn try_new_with_precomputed_values( iceberg_schema: SchemaRef, partition_spec: PartitionSpecRef, ) -> Result<Self>

Create a new RecordBatchPartitionSplitter expecting pre-computed partition values.

This is a convenience method that initializes the splitter to expect a _partition column in the input batches.

§Arguments

iceberg_schema - The Iceberg schema reference
partition_spec - The partition specification reference

§Returns

Returns a new RecordBatchPartitionSplitter instance or an error if initialization fails.

pub fn split( &self, batch: &RecordBatch, ) -> Result<Vec<(PartitionKey, RecordBatch)>>

Split the record batch into multiple record batches based on the partition spec.
