Struct RePartition 

Source 
struct RePartition {
    idx: usize,
    row_count: usize,
    batches: Vec<RecordBatch>,
}
Expand description

For use in repartitioning, track the total size and original partition index.

Do not implement clone, in order to avoid unnecessary copying during repartitioning.

Fields§

§idx: usize

Original output ordering for the partition.

§row_count: usize

Total size of the partition, for use in heap ordering (a.k.a. splitting up the largest partitions).

§batches: Vec<RecordBatch>

A partition containing record batches.

Implementations§

Source§

impl RePartition

Source

fn split(self) -> Vec<Self>

Split RePartition into 2 pieces, consuming self.

Returns only 1 partition if cannot be split further.

Source

fn add_batch(&mut self, batch: RecordBatch)
