Summary: [Rust][Parquet]
Key: ARROW-11279
URL: https://issues.apache.org/jira/browse/ARROW-11279
Project: Apache Arrow
Issue Type: Improvement
Components: Rust
Reporter: R J
In the rust implementation of an Arrow RecordBatch writer to parquet
(3.0.0-SNAPSHOT), the ArrowWriter::write call potentially allocates more memory
than required.
For a RecordBatch with m rows and n columns, ArrowWriter::write allocates m*n
definition levels, leading to m times the required memory usage.
