   ### 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)
