The Java code base originated from Apache Drill and was the first
implementation of Arrow.  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

2020-07-21 Thread Chathura Widanage
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
