There is value in having a pure java implementation separate from any C++ code base (JNI cannot be used in all contexts).

Java Arrow to C++ Arrow and vice versa
Hi all, Was there any particular reason for not writing Java Arrow as a JNI binding for CPP Arrow? What is the most straightforward and efficient way to convert a java arrow schema/table to a JNI backed C++ arrow schema/table? Regards, Chathura
