I'm interested to start a native Go implementation, since this will only run on Linux, right?

I'm interested to start a native Go implementation,

It'll be useful because it'll be faster and provide more Go style API than GLib bindings based bindings. Maintaining the implementation may be a problem.

since this will only run on Linux, right?

It's not right. The GLib bindings and bindings based on the GLib bindings can work on Linux, macOS and Windows. At least Ruby bindings can work on them. I'm developing GTK+ bindings with GObject Introspection. (gtk3 gem) The bindings can work on Linux, macOS and Windows.

But installing from source will be difficult for users. We need to provide packages for easy to use.

For macOS, it's better that we send a pull request to Homebrew.

For Windows, it's better that we build binary and make it downloadable. I'm doing it by cross-compiling on my Debian GNU/Linux machine for gtk3 gem.

Ah that's good to know about GLib. I would like to make a minimal implementation for Go that can read and write the streaming format and provide access to the raw buffers. I am not sure when I will have the time though =) Probably not until 2018...

It will also need to provide binaries for integration testing. Quite a bit of work; if we can recruit some developres from the Go community (like users or developers of InfluxDB or another database written in Go) that might be a good place to start

apacheGH-661: [Flight] JDBC: Cache failed locations (apache#662)
a956ced
## What's Changed
Instead of repeatedly trying to access locations which have failed
before, cache them and move them to the end of the list of locations to
attempt on subsequent accesses. This provides a better user experience
for Flight SQL services that return multiple locations in the
expectation that the user may not be able to access some of them (but
would have a better experience if they are).
Requires apache#494.
Closesapache#661.

I'm interested to start a native Go implementation, since this will only run on Linux, right?

It's not right. The GLib bindings and bindings based on the GLib bindings can work on Linux, macOS and Windows. At least Ruby bindings can work on them. I'm developing GTK+ bindings with GObject Introspection. (gtk3 gem) The bindings can work on Linux, macOS and Windows.
But installing from source will be difficult for users. We need to provide packages for easy to use.
For macOS, it's better that we send a pull request to Homebrew.
For Windows, it's better that we build binary and make it downloadable. I'm doing it by cross-compiling on my Debian GNU/Linux machine for gtk3 gem.

Ah that's good to know about GLib. I would like to make a minimal implementation for Go that can read and write the streaming format and provide access to the raw buffers. I am not sure when I will have the time though =) Probably not until 2018...
It will also need to provide binaries for integration testing. Quite a bit of work; if we can recruit some developres from the Go community (like users or developers of InfluxDB or another database written in Go) that might be a good place to start

apacheGH-661: [Flight] JDBC: Cache failed locations (apache#662)
a956ced
## What's Changed
Instead of repeatedly trying to access locations which have failed
before, cache them and move them to the end of the list of locations to
attempt on subsequent accesses. This provides a better user experience
for Flight SQL services that return multiple locations in the
expectation that the user may not be able to access some of them (but
would have a better experience if they are).
Requires apache#494.
Closesapache#661.
