Is there list writer in Java?

Hello, all

I’m new to Apache Arrow, and checking whether it supports most of data types. It seems like that there’s no implementation for list<decimal> writer in UnionListWriter yet. Is there other way?

Thanks.

Teddy Choi.

Siddharth, thanks for quick answer. I can work on this issue. It's a good chance for my first Arrow contribution. :)

Hi Teddy,

Yes UnionListWriter currently doesn't support writing decimals into list
vector. Basically we are missing APIs like UnionListWriter.decimal() which
will return a DecimalWriter(we already have this) and the latter can be
used to write decimals in list. I'd suggest you to go ahead and file a JIRA
on https://issues.apache.org/.

Please feel free to take it up if you are interested in contributing to
Arrow codebase.

Thanks,
Siddharth
