Build Status License Docker Contributors

a fast NoSQL DB, that uses the same RESP protocol and capable to store terabytes of data, also it integrates with your mobile/web apps to add real-time features, soon you can use it as a document store cause it should become a multi-model db. `Redix` is used in production, you can use it in your apps with no worries.

Features

Why

I started this software to learn more about data modeling, data structures and how to map any data to pure key value, I don’t need to build a redis clone, but I need to build something with my own concepts in my own style. I decided to use RESP (redis protocol) so you can use Redix with any redis client out there.

Install

Configurations

It is so easy to configure Redix, there is no configuration files, it is all about running ./redix after you download it from the releases, if you downloaded i.e ‘redix_linux_amd64’ and unziped it.

$ ./redix_linux_amd64 -h

  -engine string
        the storage engine to be used, available (default "leveldb")
  -http-addr string
        the address of the http server (default ":7090")
  -resp-addr string
        the address of resp server (default ":6380")
  -storage string
        the storage directory (default "./redix-data")
  -verbose
        verbose or not
  -workers int
        the default workers number (default ...)

Examples


# i.e: $mykey1 = "this is my value"
$ redis-cli -p 6380 set mykey1 "this is my value"

# i.e: $mykey1 = "this is my value" and expire it after 10 seconds
$ redis-cli -p 6380 set mykey1 "this is my value" 10000

# i.e: echo $mykey1
$ redis-cli -p 6380 get mykey1

# i.e: $mymap1[x] = y
$ redis-cli -p 6380 hset mymap1 x y

# i.e: $mymap1[x] = y and expires it after 10 seconds
$ redis-cli -p 6380 hset mymap1 x y 10000

# i.e: sha512 of "test"
$ redis-cli -p 6380 encode sha512 test

# you want to notify an endpoint i.e: "http://localhost:800/new-data" that there is new data available, in other words, you want to subscribe a webhook to channel updates.
$ redis-cli -p 6380 webhookset testchan http://localhost:800/new-data

# add data to a list
# i.e: [].push(....)
$ redis-cli -p 6380 lpush mylist1 "I'm Mohammed" "I like to Go using Go" "I love coding"

# search in the list
$ redis-cli -p 6380 lsrch mylist1 "mo(.*)"

Supported Commands

Redix doesn’t implement all redis commands, but instead it supports the core concepts that will help you to build any type of data models on top of it, there are more commands and features in all next releases.

# Basic

# Strings

# HASHES

I enhanced the HASH MAP implementation and added some features like TTL per nested key, also you can check whether the hash map itself exists or not using HEXISTS <hashmapname> or a nested key exists using HEXISTS <hashmapname> <keyname>.

# LIST

I applied a new concept, you can push or push-unique values into the list, based on that I don’t need to implement two different data structures, as well as, you can quickly iterate over a list in a high performance way, every push will return the internal offset of the value, also, the iterator lrange will tell you the next offset you can start from.

# SET

# Pub/Sub

Redix has very simple pub/sub functionality, you can subscribe to internal logs on the * channel or any custom defined channel, and publish to any custom channel.

# Ratelimit

# Utils

some useful utils that you can use within your app to remove some hassle from it.
