Subject: Re: [openstack-dev] [tc] supporting Go


Go is a production language used by Google, Dropbox, many many web startups, and in fact Fortune 500 companies.

Using a package manager won't buy us anything, and like Clint raised, the Linux distros are way too slow in picking up new Go releases. In fact, the standard way of installing Rust also does not use a package manager:

It would be nice if we only need to write code in one language. But in the real world the "nicer" & "easier" languages like Python & Perl are also the slower ones. I used to work for an investment bank, and our system was developed in Perl, with performance critical part rewritten in C/C++, so there really is nothing wrong with mixing languages. (But if you ask me, I would strongly prefer Go than C++.)

I hope that the packaging technologies are considered as part of the TC evaluation of a new language. While many alternative approaches are available, a language which could not be packaged into RPM or DEB would be an additional burden for distro builders and deployers.

Does Go present any additional work compared to Python in this area ?

If it ends up being a better implementation than the reference OpenStack Swift implementation, it will win anyways and perhaps Swift will start to look more like the rest of the projects in OpenStack with a standardized API and multiple plugable implementations.
