``sh`
npm install aedes aedes-persistence-redis --save
Please check UPGRADE.md when upgrading from a previous version.
Creates a new instance of aedes-persistence-redis.
It takes all the same options of ioredis,
which is used internally to connect to Redis.
This constructor creates two connections to Redis.
Example:
`js`
aedesPersistenceRedis({
port: 6379, // Redis port
host: '127.0.0.1', // Redis host
family: 4, // 4 (IPv4) or 6 (IPv6)
password: 'auth',
db: 0,
maxSessionDelivery: 100, // maximum offline messages deliverable on client CONNECT, default is 1000
packetTTL: function (packet) { // offline message TTL, default is disabled
return 10 //seconds
}
})
Alternatively, you can pass in an externally created Redis connection using the
conn option. This can be useful when connecting to a Redis cluster, for example.
Example:
`js`
aedesPersistenceRedis({
conn: new Redis.Cluster([{
port: 6379,
host: '127.0.0.1'
}, {
port: 6380,
host: '127.0.0.1'
}]),
cluster: true
})
The same as above but with cluster option:
`js``
aedesPersistenceRedis({
cluster: [{
port: 6379,
host: '127.0.0.1'
}, {
port: 6380,
host: '127.0.0.1'
}]
})
v4 has changed the subscriptions key schema to enhance performance. Please check related PR for more details.
