Over the weekend I added preliminary Parquet support to DataFusion (it only
supports int/float primitives and UTF8 so far). This was possible due to
the great work happening with the parquet-rs crate.
Integrating this with the current Rust version of Arrow was simple and I
have now started running

Hey all, given that several people are busy in June, let's way until the

Thanks!

Hi all,
I’ve been doing some work lately with Spark’s ML interfaces, which include
sparse and dense Vector and Matrix types, backed on the Scala side by
Breeze. Using these interfaces, you can construct DataFrames whose column
types are vectors and matrices, and though the API isn’t terribly rich,
As far as I know, there is an implementation of tensor type in C++/Python
already. Should we just finalize the spec and add implementation to Java?
On the Spark side, it's probably more complicated as Vector and Matrix are
not "first class" types in Spark SQL. Spark ML implements them as UDT
(user
The tensor type in the c++ api is a stand-alone object afaict, Phillip and
I were unable to construct an arrow column of them. I agree that it’s a
good starting point, one interpretation of what I’m suggesting is that we
take it as the reference implementation, add it to the spec, and write the

There is nothing specified yet as far as a *column* of
ndarrays/tensors. We defined Tensor metadata for the purposes of
IPC/serialization but mad

My gut feeling is that such a column type should specify both the shape and
primitive type of all values in the column. I can’t think of a common use
case that requires differently shaped tensors in a single column.
Can anyone here come up with such a use case?
If not, I can try to draft a propos

I'm also trying to use arrow-rs in my project and would like to contribute
to arrow-rs, can anybody give me contributor permission?

Hello Renjie,
I can give you contributor permissions on JIRA so you can assign issues to
yourself. I would need to know your JIRA id for that.
Code contributions happen per pull request on github. Just fork the project,
open a new branch and once it's ready: make a pull request to the main arro
