Hi,
I was looking at the recent checkin for arrow kernels, and started to think of
how they would work alongside Gandiva.
Here are my thoughts :
1. Gandiva already has two high-level operators namely project and filter, with
runtime code generation
* It already supports 100s of functions

I’m also interested in the Parquet/Arrow integration and may help there.
This is however a relative large feature and I’m not sure if it can be done
in 0.13.
Another area I’d like to work in is high level Parquet writer support. This
issue has been discussed several times in the past. People
Hi All,
The focus for me for 0.13.0 is SIMD. I would like to port all the "ops" in
"array_ops" to the new "compute" module and leverage SIMD for them all. I have
most of this done in various forks.
Past 0.13.0 I would really like to work toward getting Rust running in the
integration tests.

Even if zeromq did make more sense, we couldn't take it on as a
dependency because of non-ASF-compatible licenses
Java zeromq: MPL 2.0

Would zeromq make more sense than gRPC?
Thanks,

Hi David,
I think allowing to send application-specific ancillary data in addition
to Arrow data makes sense.
(I'm also wondering whether the choice of gRPC is appropriate at all -
the current C++ hacks around "zero-copy" are not pretty and they may not
translate to other languages either)
Hi all,
We've been evaluating Flight for our use, and we're wondering if the protocol
is still open to extensions, as having a few application-defined metadata
fields would help our use cases a lot.
(Apologies if this is a repost - was having issue with the spam filter.)

Thanks for bringing this up Andy.
I'm unemployed/on recovery leave, so I've had some surplus time to work on
Rust.
There's a lot of features that I've wanted to work on, some which I've
spent some time attempting, but struggled with. A few block additional work
that I could contribute.
In
I was curious what our Rust committers and contributors are excited about
for 0.13.0.
The feature I would most like to see is that ability for DataFusion to run
SQL against Parquet files again, as that would give me an excuse for a PoC
in my day job using Arrow.
I know there were some efforts
