**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** Parquet writing performance is not very good. The `arrow_writer` microbenchmark shows throughput for a batch of primitives to be around 200MiB/s. For a column-oriented format that seems rather low, but a profiling run shows no obvious single bottleneck. **Describe the solution you'd like** Investigate and improve the performance. **Describe alternatives you've considered** <!-- A clear and concise description of any alternative solutions or features you've considered. --> **Additional context** <!-- Add any other context or screenshots about the feature request here. --> -- This is an automated message from the Apache Git Service.
