在Java中将Arrow转换为Parquet，反之亦然

Question

I have been looking at ways to convert arrow to parquet and vice versa in Java.

Even though the Python library for arrow has full support for the mentioned conversion, I can hardly find any documentation for the same in Java.

Has anyone come across such feature in arrow/parquet Java libraries?

Answer 1

There isn't a native Java reader that is part of Arrow. There has been some recent discussion on creating one and the incubating Apache Iceberg project might also have one

Dremio has some code that potentially does the conversion

The core parquet-mr project also appears to have code for conversion .
