reDIStributor

[redis distributor] reDIStributor is a nodeJS library that distributes redis commands to instances by rules. Default behaviour divides your server instances into masters and slaves. It then sends all write-type commands to the masters and all read-type commands to the slaves.

It's wrapping the standard node-redis library (along with hiredis), so sending commands follows exactly the same as before.

installing

npm install redistributor

initializing

var Redistributor = require('redistributor');
var redisClient = new Redistributor();

adding servers

redisClient._addServer('masters', { host:'127.0.0.1', port: 6379, options: {}});
redisClient._addServer('slaves', { host:'localhost', port: 6379, options: {}});

sending commands

redisClient.set(
    'redistributor_test_1', 
    '1', 
    function(err, reply) { 
        console.log(err, reply); 
    }
);

redisClient.get(
    'redistributor_test_1',
    function(err, reply) {
        console.log(err, reply); 
    }
);

defining the rule by which to choose a server from the determined list

redisClient._distributeBy('first');
redisClient._distributeBy('roundRobin');
redisClient._distributeBy('random');

enabling debug

redisClient._debug = true;
