GitHub user amoeba added a comment to the discussion: dataset write api
I see now, thanks. I think there are two options, 1. The JNI bindings need to be extended to support setting custom [DatasetWriteOptions](https://arrow.apache.org/docs/cpp/api/dataset.html#_CPPv4N5arrow7dataset29FileSystemDatasetWriteOptionsE). This might let you do what you want though I'm not totally sure. 2. (Probably easier) Create a new reader for each file you want to write and call into `DatasetFileWriter.write` once for each reader GitHub link: https://github.com/apache/arrow-java/discussions/1025#discussioncomment-15975456 ---- This is an automatically sent email for [email protected].
