Radix

Radix is a full-featured Redis client for Go. See the GoDoc for documentation and general usage examples.

This is the third revision of this project, the previous one has been deprecated but can be found here.

This project's name was recently changed from radix.v3 to radix, to account for go's new module system. As long as you are using the latest update of your major go version (1.9.7+, 1.10.3+, 1.11+) the module-aware go get should work correctly with the new import path.

I'm sorry to anyone for whom this change broke their build, I tried very hard to not have to do it, but ultimately it was the only way that made sense for the future. Hopefully the only thing needed to fix the breakage is to change the import paths and re-run 'go get'.

Installation and Usage

Module-aware mode:

go get github.com/mediocregopher/radix/v3
// import github.com/mediocregopher/radix/v3

Legacy GOPATH mode:

go get github.com/mediocregopher/radix
// import github.com/mediocregopher/radix

Testing

# requires a redis server running on 127.0.0.1:6379
go test github.com/mediocregopher/radix/v3

Features

• Standard print-like API which supports all current and future redis commands

• Support for using an io.Reader as a command argument and writing responses to an io.Writer.

• Connection pooling

• Helpers for EVAL, SCAN, and pipelining

• Support for pubsub, as well as persistent pubsub wherein if a connection is lost a new one transparently replaces it.

• Full support for sentinel and cluster

• Nearly all important types are interfaces, allowing for custom implementations of nearly anything.

Benchmarks

Thanks to a huge amount of work put in by @nussjustin, and inspiration from the redispipe project and @funny-falcon, radix/v3 is significantly faster than most redis drivers, including redigo, for normal parallel workloads, and is pretty comparable for serial workloads.
