Integer Compression Libraries for Go

Encoding

This is a set of integer compression algorithms implemented in Go. It is an (incomplete) port of the JavaFastPFOR by Dr. Daniel Lemire.

For more detailed benchmark results please see http://zhen.org/blog/benchmarking-integer-compression-in-go/

encoding's Issues

int64 support

Would it be possible to add int64 encoding support where possible?

I couldn't run

hello, I'm trying to replace the fastPFor java code with golang, but when the array I sent in my java code is outputting, I'm getting an error over golang.

The error I get is: fastpfor/Compression Length = 0. No work done.

What exactly could be the reason, thanks in advance.

go get fails with asm: "".bitlen: invalid instruction: 00006

when doing go get github.com/zentures/encoding, it fails with:

asm: "".bitlen: invalid instruction: 00006 (/home/.../go/pkg/mod/github.com/zentures/[email protected]/bitlen_amd64.s:6) JEQ Z1 asm: assembly failed

Using SIMD accelerated functions (x64)

There is a Go library that provides SIMD-accelerated packing and unpacking functions. It seems that some of the codecs of this library could make use of such functions.

Is dataence/encoding the same repository?

There are import paths that points to github.com/dataence/encoding/* all over the library. It seems as you moved this repository from dataence to zentures and you forgot to change to paths. Am I right? I could open a quick PR and fix the paths.
