Subject Arrow 0.3 release timeline
Date Mon, 03 Apr 2017 18:25:02 GMT
hi folks,

We've been making excellent progress toward the 0.3 release -- 123
patches in since 0.2, which was released a little over 6 weeks ago.

Here is the JIRA to help track related issues:

Once ARROW-510 (, thanks
Leif!) has been resolved, we'll have all of the date and time types
reconciled which was one of the major goals for the release. It would
be nice to get the fixed size binary working end to end (ARROW-634),
but if that slips to 0.4, I don't think it's a big deal.

I know there are a number of other Java patches in flight; I will let
others comment on their status.

What remains on the C++ and Python side

* Decimal patch (ARROW-655)
* Some date and time compatibility with pandas
* Packaging issues on Linux / OS X, e.g. wheels for pyarrow that can
be compiled against / linked to by thirdparties
* Windows support for Python
* Some miscellanea parquet-cpp integration improvements

If all goes well, we may be able to cut an RC next week or the week after.

Is there anything else that others would like to see go into the 0.3
release? I think we may be able to make the 0.4 release more quickly
(~1 month or less after 0.3) as we finish out some of the additional
compatibility issues (dictionaries in IPC stream/file format is a
significant one).
