### Describe the usage question you have. Please include as many useful details as possible. We are currently using arrow's parquet write API to write parquet files. It was found that different APIs will bring different performance data. We wrote a simple benchmark to read 1GB of tpcds `store_sales ` data [here](https://github.com/JkSelf/gluten/blob/1015756c07d326dc301d2b1824c8c40dc59b021b/cpp/velox/benchmarks/ParquetWriteBenchmark.cc#L220). Then use `FileWriter#WriteTableAPI()`, `FileWriter#WriteRecordBatch()` to write data respectively, and found the `FileWriter#WriteTableAPI()` need **800s** and the `FileWriter#WriteRecordBatch()` only need **4.9s** . The strange thing here is why the performance of WriteTableAPI is so poor. I want to ask, is the way I use it wrong? ### Component(s) C++, Parquet -- This is an automated message from the Apache Git Service.
