Subject Re: How to get started with using the Arrow Java API?
Date Mon, 20 Jul 2020 08:30:26 GMT
Hi Xiaozhen

Sorry in advance for the self-promotion. 

I had the same issue, hence I wrote down what I figured out about the Java API in this blog
post: https://www.infoq.com/articles/apache-arrow-java/ <https://www.infoq.com/articles/apache-arrow-java/>

Another blog post can be found here: https://github.com/animeshtrivedi/blog/blob/master/post/2017-12-26-arrow.md
<https://github.com/animeshtrivedi/blog/blob/master/post/2017-12-26-arrow.md>

And last but not least, there is some more documentation inside the source code: https://github.com/apache/arrow/tree/master/java
<https://github.com/apache/arrow/tree/master/java>
In particular: 
- https://arrow.apache.org/docs/java/vector.html <https://arrow.apache.org/docs/java/vector.html>
- https://arrow.apache.org/docs/java/vector_schema_root.html <https://arrow.apache.org/docs/java/vector_schema_root.html>
are good starting points for exploring the API.

Best regards
Joris

Current we’re trying to use Arrow in our system (now we’re trying arrow for transferring
data between JVM and a python process, but maybe eventually we will adopt Arrow throughout
our system).

very informative as a starting point.

<https://arrow.apache.org/docs/java/ipc.html>), but these pages are not indexed and
can only be discovered by searching. Is this something that is being worked on?
