hi folks,
In a prior mailing list thread from February [1] I brought up some
work I'd done in C++ to create an API to define custom data types that
can be embedded in built-in Arrow logical types. These are serialized
through IPC by adding special fields to the `custom_metadata` member
of Field in

hi Joris,
Somewhat related to this, I want to also point out that we have C++
extension types [1]. As part of this, it would also be good to define
and document a public API for users to create ExtensionArray
subclasses that can be serialized and deserialized using this
machinery.
As a motivating

hi Micah,
This sounds like a reasonable proposal, and I agree in particular for
regular contributors that it makes sense to close PRs that are not
close to being in merge-readiness to thin the noise of the patch queue
We have some short-term issues such as various reviewers being busy
lately (e.g
Missed the email of Wes, but yeah, I think we basically said the same.
Answer to another question you raised in the notebook:

Our backlog of open PRs is slowly creeping up. This isn't great because it
allows contributions to slip through the cracks (which in turn possibly
turns off new contributors). Perusing PRs I think things roughly fall into
the following categories.
1. PRs are work in progress that never got com
Hi Rick,
Thanks for exploring this!
I am still quite new to Parquet myself, so the following might not be fully

dask to write the different pieces of a Parquet dataset using pyarrow, we
need the following functionalities:

hi Richard,
We have been discussing this in
https://issues.apache.org/jira/browse/ARROW-1983
All that is currently missing is (AFAICT):
* A C++ function to write a vector of FileMetaData as a _metadata file
(make sure the file path is set in the metadata objects)
* A Python binding for this

I am hoping to help improve the use of pyarrow.parquet within dask
(https://github.com/dask/dask). To this end, I put together a simple notebook
to explore how pyarrow.parque
