Hello,
Python 2.7 will soon be end-of-life. It will stop being supported upstream on January 1st, 2020. Many projects have started publishing Python 3-only releases (see https://python3statement.org/). PyArrow will soon stop supporting Python 2 as well, perhaps at the end of the year. In the meantime, as build times on public Continuous Integration services have continuously ballooned, we could start by not testing Python 2 anymore on those services. It would easy build times a bit. Testing would be done as a best effort thing, possibly by users of development versions. Regards Antoine.
