struct ArrowRowGroupWriter {
writers: Vec<ArrowColumnWriter>,
schema: SchemaRef,
buffered_rows: usize,
}
Expand description
Encodes [RecordBatch
] to a parquet row group
Note: this structure is created by ArrowRowGroupWriterFactory
internally used to
create ArrowRowGroupWriter
s, but it is not exposed publicly.
See the example on ArrowColumnWriter
for how to encode columns in parallel
