ZEDIS

A lightweight zeromq and seld based replacement for Redis. <90 LOC focused on a portable cross language simple storage system. No need to run a full service.

Zedis is opinionated and limited. With ZEDIS you can only READ and WRITE key values pairs. All writes overwrite past values.

Really Fast reads < 250µs for ~2 MB json payload.

Pretty Fast writes < 18ms for ~2 MB json payload.

Setting Port

Now you can set the port/socket that zedis will be available on. If no port is specified zedis will fallback on 5555

bash zedis 6677

Commands

Get values

GET key

Return the string values of the key. Returns b'Error occurred: InvalidKey' if key does not exist

Set values

SET key value Insert a key value. If the key already exists the value will be overwritten.

Remove values

DEL key

Delete a key and it's value from zedis. This will also return the last known value of the key.

Show keys

KEYS

This retrns a JSON format list of all of the keys. This is ineffiecent, it iterates through the whole DB and then concats the key names togther. Do not use if you have more than 1000 keys if you want instant results.

Query

PRE keyprefix

Returns all keys with that prefix. So "A" will return "Alpha", "Awesome"... this is case sensitive.

Python3 client example

```python import zmq import json

port = "5555"

context = zmq.Context() socket = context.socket(zmq.REQ) socket.connect("tcp://localhost:%s" % port)

socket.send_string("SET david richard blyn holtz");socket.recv()

'done.'

socket._string("GET david");socket.recv()

'richard blyn holtz'

jsonblob = json.dumps({"example": "you can store seralized JSON"}) socket.send_string("SET js "+jsonblob);socket.recv()

'done.'

socket.send_string("GET js") json.loads(socket.recv())

{u'exmple': u'lorem ipsum...'}

socket.send_string("DEL js");socket.recv();socket.recv()

b'2 yo yo'

ADDING A BUNCH OF KEYS

for x in range(0, 100): socket.send_string("SET "+str(x)+" "+str(x)+" yo yo") socket.recv()

socket.send_string("PRE 1");socket.recv()

b'["1", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19"]'

socket.send_string("KEYS");socket.recv()

b'["0", "1", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20", "21", "22"]'
