@tustvold if we want it to perform well with glibc memory allocator, it seems that replacing `vec<vec>` by a single vec and extra metadata for `ColumnIndexBuilder.min_values` and `ColumnIndexBuilder.max_values` https://github.com/apache/arrow-rs/blob/f7101ec3a2b37c436f4554c28fa2d0a05de533ff/parquet/src/file/metadata.rs#L886-L887 can help to reduce allocation of small vectors. -- This is an automated message from the Apache Git Service.
