Hi
I have a Golang server with a bunch of structs. The server was serving data
over JSON happily till now. Suddenly, there is a need for using proto.
Is there a way to automatically generate a .proto file given a set of
golang structs ? Some structs contain arrays of instances of some of these

Hello gophers,
We have just released go1.7rc4, a release candidate for Go 1.7.
It is cut from release-branch.go1.7 at the revision tagged go1.7rc4.
Please help us by testing your Go programs with the release, and report any
problems using the issue tracker:

Hi Nathan,
Thank you for reply. Yes I thought about this approach. But it looks a
little ugly. Every time you add new struct that can be used – you should
don't forget to update switch. But it seems that there is no other way.
Thank you!

If I remember correctly, the original idea for the CAT technology was to
have "cache smashing" workloads on the same machines as other workloads.

Hey Brad!
Yes, end users. Generally, we can't make assumptions about what they have
installed locally (e.g. Go toolchain) and I would like to provide a way for
folks to "click a button" and get a fully symbolized profile to send to
us. Doing this inside of an existing Go program would be ideal.
Viacheslav,
Your best bet here in my opinion is to have an intermediate object that
contains type information which you Unmarshal into first to get the
concrete type. Then, you have a switch to Unmarshal the remainder of the
object into the real deal. We did a similar mechanic to this on Dock
Oh, interesting call out. Thanks Brad. For some reason I assumed pprof

It used to be. It was rewritten in Go.

You can vendor that into the Docker daemon and have the server profile

Hi,
I want to marshal/unmarshal object for saving in key/value storage.
The question is: if I got this object using function, that accepts
interface type, lets say for example: base.Pricer. And there are more than
one type struct that satisfy this interface. I know while marshaling what
type

Or vendoring any dependency which can be mirrored to git, which is
essentially all of them.

Set up an SLA for the service:
* 99th percentile: 99 of 100 requests are under 5ms processing time.
* 99.99th percentile: of 10.000 requests are under 25ms processing

I think the high bit here is that the Go community is very aggressive about
GC latency. Go has large
users with large heaps, lots of goroutines, and SLOs similar to those being
discussed here. When
they run into GC related latency problems the Go team works with them to
root cause and address

Consul and etcd use Boltdb (https://github.com/boltdb/bolt) which uses an

The nature of the cache is very important. It is easy to create and manage

Wow men, excellent your job.
I will try to test, is very clean your example.
I will post my example when finish the test.

If you can perform your task with 10 independent processes, it means that
they are not competing for the same resource, and consequently, it should
run as well, if run within the same process. It all depends whether there
are critical paths where a common resource needs to be locked. And a

The best way is to create a prototype, mock your worst situation, and measure
it.
