Hi,
how can I load a Spark dataframe into Arrow using Scala?
I've seen some older posts regarding this subject, but am hoping that there
has been some development around this...
I'd like to load a Spark dataframe into Arrow and then use the Gandiva
project to do some analytics on that,
thanks in

Hi,
Do you want to collect a Spark DataFrame into Arrow format on a single
machine or do you still want to keep the data distributed?
Small update:

We still build the Python wheels on CentOS 5. This should be no problem as
llvmlite can also be build on that OS.
It looks like there will be a new Linux Python wheel standard soon where we
will upgrade to
hi folks,
Tuesday's update: it looks like we're going to be able to close out
the C++ and Python dev work without any issues before the end of the
week. I'm going to make some tweaks to the website per the JIRAs that
are available but that won't take long.

That sounds great to me. I'll make sure I'm able to build and sign
artifacts this week and surface any issues I find along the way. Looking
forward to a smooth release!

While I'm not a level 83 LLVM wizard like Antoine :) I have a small amount
of experience with it and would also be happy to review/merge patches.
Having Gandiva in arrow will simplify packaging and building the library,
which IME has always been annoying with large cross-platform and
cross-languag

hi Richard,
I might start here in the Spark codebase to see how Spark SQL tables

Hi,
I'm wondering what we should do with the Rust implementation for the 0.10.0
release. I would like to have an official release pushed to crates.io for
sure.
Since the Rust implementation is so new there isn't much demand for new
features yet so I think it is more important to focus on changes
+1 for pushing to crates.io.

Seems fine to cut a release to crates.io with the 0.10.0 release. Do
you want to use the same version numbers?

Yes, I think that makes sense. So should I go ahead and do that whenever
now or is there more involved?
Also, I'm the only person that can release to crates.io right now so that
is something we should fix. I can grant release privileges to others.

If you could wait until the 0.10.0 release vote has been conducted
that would be best. Ideally the crates.io release should be performed
using the source release tarball. If it cannot, then open a bug report
so that it can be fixed for next time.

That's fine. I'll create a PR for updating the version number to 0.10.0 and
I think we should be good to release from the source tarball.
