ArrowWriteSchemaPlan

parquet::arrow::arrow_writer

Struct ArrowWriteSchemaPlan 

Source 
struct ArrowWriteSchemaPlan {
    fields: Box<[ArrowTopLevelWriterSpec]>,
    leaves: Box<[ColumnDescPtr]>,
}
Expand description

Immutable schema glue shared by every row group.

This deliberately caches only schema fields and Parquet descriptors, never arrays or per-batch level/value plans.

Fields§

§fields: Box<[ArrowTopLevelWriterSpec]>§leaves: Box<[ColumnDescPtr]>
