That's good. Is C++ writer code also available?

The C++ reader is written completely from scratch. It does not need underlying
java reader. It understands the ORC file specification and the format as such
does not have anything to do with java. The metadata layer is all protobuf
based which can be read in C++ as well.

But won't C++ Orc reader need underlying Java? Or the current Apache Orc C++
code does not work?

Hi Sean
We are still in the process of moving ORC java code out of Apache Hive project.
The java code will eventually land in the Apache Orc project. At this point
only the C++ reader for ORC is in Apache Orc master.

Hi community,
I am new to Apache Orc. I have the impression that Orc was originally developed
in Java, and I can see that there are Java code under Hive Orc:
http://svn.apache.org/viewvc/hive/trunk/ql/src/java/org/apache/hadoop/hive/ql/io/orc/
But when I check out the Apache Orc git, I did not see any any Java code, and
only C++:
https://github.com/apache/orc/tree/master
Can anyone clarify if the Orc is rewritten completely in C++, or the C++ code
is just a wrapper on top of the old Java implementation? If the later, then why
there is no Java code in Apache Orc git?
Thanks a lot!
Best,Sean
