Especially with Arrow support landing in Spark (SPARK-13534), it would
be helpful to combine efforts between Python and R on this front. I
also have a long list of improvements to the Feather format that will
be substantially simpler once library(feather) is depending on the
main Arrow libraries.
I also sent a note about it to the dev list a month ago. Still have a huge
internal need and interested in helping push this along where we can.
Unfortunately, our team is more focused around Spark and doesn't have much
experience working with the R community.

Hello all,
I'd like to propose the 1st release candidate (rc1) of Apache Arrow version
0.5.0. This is a major release consisting of 129 resolved JIRAs [1].
The source release rc1 is hosted at [2].
This release candidate is based on commit

Hi,
I started looking into the projects Parquet and Arrow. Looks very promising
to me.
I also came across PyArrow and the Parquet-Arrow integration in Python. Is
there something similar available for Java?

I see. It took me a while to understand, but it all made sense when I
realized that we are not looking at one Map instance but multiple
rows, each with a Map instance, and the constituents parts of those
Maps are stored end-to-end.

So in the first case we have buffer structure:

Hello all,
I saw the notes come through from today's call:

This year I've been working on parallel R on datasets in the 100+ GB range,
and have found that loading

Because it doesn’t take advantage of the fact that (a) keys can be re-ordered,
(b) keys are unique.
So, another viable physical representation would be Struct, List>,
with the keys sorted. If keys are constant width and in contiguou
