+# redis-benchmark-go
+
+## Overview
+
+This repo contains code to mimic redis-benchmark capabilities in go solely for OSS redis cluster. 
+
+## Installation
+
+The easiest way to get and install the Subscriber Go program is to use
+`go get` and then `go install`:
+```bash
+# Fetch this repo
+go get github.com/filipecosta90/redis-benchmark-go
+cd $GOPATH/src/github.com/filipecosta90/redis-benchmark-go
+make
+```
+
+## Usage of redis-benchmark-go
+
+```
+$ redis-benchmark-go --help
+Usage of redis-benchmark-go:
+  -a string
+        Password for Redis Auth.
+  -c uint
+        number of clients. (default 50)
+  -d uint
+        Data size of the expanded string __data__ value in bytes. The benchmark will expand the string __data__ inside an argument with a charset with length specified by this parameter. The substitution changes every time a command is executed. (default 3)
+  -debug int
+        Client debug level.
+  -h string
+        Server hostname. (default "127.0.0.1")
+  -l    Loop. Run the tests forever.
+  -n uint
+        Total number of requests (default 100000)
+  -p int
+        Server port. (default 12000)
+  -r uint
+        keyspace length. The benchmark will expand the string __key__ inside an argument with a number in the specified range from 0 to keyspacelen-1. The substitution changes every time a command is executed. (default 1000000)
+  -random-seed int
+        random seed to be used. (default 12345)
+```
+
+## Sample output - 10M commands

+```
+$ redis-benchmark-go -p 20000 --debug 1  hset __key__ f1 __data__
