luoyuxia opened a new issue, #735: URL: https://github.com/apache/arrow-java/issues/735
### Describe the enhancement requested I'm working on https://github.com/alibaba/fluss/issues/107 which enable convert Fluss arow structure data to Parquet directly but found the API missing in here. Althogh #14151 supports to write from ArrowReader to file, it read from the ArrowReader, write and close the file direclty. But it's in a very coarse-grained , we almost have no control about the writing. Sometime, we want to control when to close the written parquet. Also it require `ArrowReader`, but if the arrow RecordBatch is read continuously from remote server . It's not easy to constuct a `ArrowReader`. So, I think we may need to support the interface to write Arrow RecordBatch to Parquet via [virtual ::arrow::Status WriteRecordBatch(const ::arrow::RecordBatch& batch) = 0](https://github.com/apache/arrow/blob/c506b0806bd2b90410400d349a16bc4a5b1dd51c/cpp/src/parquet/arrow/writer.h#L125) Just to as a show case, the api may look like: ``` public class ArrowBatchParquetWriter { void write(RecordBatch recordbatch); void close() } ``` -- This is an automated message from the Apache Git Service.
