Re: Deprecating the Python bindings

[Armand Grillet]

Hi all,

We now have ongoing work to update all our Python components to Python 3
except for the bindings. We have taken care of the build system to work
with both the Python 2 and 3 codebase thus the bindings do not need to be
deprecated/updated before Python 2 EOL (i.e. 2020, and even then I do not
know if an update will be necessary).

I thus do not think that we need to deprecate or move the bindings to a
separate repo. However, the fact that the bindings are not maintained is a
problem. The code to build them is not straightforward

and I do not know anyone who has the time or interest to update or simplify
the process in the future.

Another approach could be to move the bindings from the `mesos` git repo to a 
separate repo (either the ASF or in the `mesos` GitHub org). This could 
decouple it from the main Mesos build infrastructure and create a project for a 
Python community to coalesce around. I think there's value in nominating an 
official Python binding, but maybe we don't have to carry that in the same git 
repo and build system.

Andrew,

Is it one of the reasons for deprecating this binding the lack of
interest of Mesos community? If the answer is yes, let me try to boost
the maintenance of this biding.

Re: Deprecating the Python bindings

[Heer, Christoph]

Hi,

within SAP, we still use the Python bindings for our own productive Mesos 
framework. There a multiple different pure Python implementations available but 
especially this wide choice, different capabilities, unclear update 
frequencies, available documentation and mixed quality makes the switch hard 
and brings a lot of uncertainties. With the Python binding we had always a 
reliable pice software that was part of Mesos and therefore covered somehow 
with testing and included in release decisions.

I understand the motivation behind the deprecation and removal. But I'm afraid 
of the drop of the 'official' Python bind as it will probably deter people to 
build Mesos frameworks with Python. Maybe it would make sense to promote one 
implementation as recommended and include it into testing and release decisions 
but I see also the point to give flexibility and choices.

Best regards,
Christoph

Re: Deprecating the Python bindings

[Vinod Kone]

One of the production users that I know who used to depend on python
bindings were https://github.com/douban.

Also, apache aurora used to have an executor that depended on python
bindings.

I don't know what their dependencies are these days w.r.t python bindings.

Deprecating the Python bindings

[Andrew Schwartzmeyer]

Hi all,

There are two parallel efforts underway that would both benefit from 
officially deprecating (and then removing) the Python bindings. The 
first effort is the move to the CMake system: adding support to generate 
the Python bindings was investigated but paused (see MESOS-8118), and 
the second effort is the move to Python 3: producing Python 3 compatible 
bindings is under investigation but not in progress (see MESOS-7163).


Benjamin Bannier, Joseph Wu, and I have all at some point just wondered 
how the community would fare if the Python bindings were officially 
deprecated and removed. So please, if this would negatively impact you 
or your project, let me know in this thread.


Thanks,

Andrew Schwartzmeyer
