Hi,

I=E2=80=99m a contributor to the Texera (https://github= .com/Texera/texera) project, which is an online big data analytics syst= em providing visual and interactive workflow. Current we=E2=80=99re trying = to use Arrow in our system (now we=E2=80=99re trying arrow for transferring= data between JVM and a python process, but maybe eventually we will adopt = Arrow throughout our system).

However, there seem= to be very few tutorials regarding the Java API of Arrow, and the document= ation provided by Arrow=E2=80=99s official website only has Maven JavaDoc, = which is not very informative as a starting point.

So where can I find the kind of documentation like that of C++ and Python= API where many examples are shown? I=E2=80=99ve noticed there are a few pa= ges like this for Java (https://arrow.apache.org/docs/java/ipc.html), bu= t these pages are not indexed and can only be discovered by searching. Is t= his something that is being worked on?

=C2= =A0

Thank you.

<= u>=C2=A0

Best,

Xiaozhen Liu
