/*
Parallel processing with ordered output in Go
(you can use this pattern by importing https://github.com/MarianoGappa/parseq)

This example implementation is useful when the following 3 conditions are true:
1) the rate of input is higher than the rate of output on the system (i.e. it queues up)
2) the processing of input can be parallelised, and overall throughput increases by doing so
3) the order of output of the system needs to respect order of input

- if 1 is false, KISS!

/*
This snippet is an example of backpressure implementation in Go.
It doesn't run in Go Playground, because it starts an HTTP Server.

The example starts an HTTP server and sends multiple requests to it. The server starts denying
requests by replying an "X" (i.e. a 502) when its buffered channel reaches capacity.

This is not the same as rate-limiting; you might be interested in https://github.com/juju/ratelimit
or https://godoc.org/golang.org/x/time/rate.

Go (Golang) Standard Library Interfaces (Selected)

This is not an exhaustive list of all interfaces in Go's standard library. I only list those I think are important. Interfaces defined in frequently used packages (like io, fmt) are included. Interfaces that have significant importance are also included.

All of the following information is based on go version go1.8.3 darwin/amd64.
