# Read and write Redis in Duaer

In Duaer, Redis defaults to Operation Info. Use Set, Get, and other operations for keys. You need a redis credential.
## Set a key

1. Create a redis credential.
2. Search for Redis, connect it after the previous node, and select that credential.
3. Set Operation to Set.
4. Enter Key and Value. Key Type defaults to Automatic.
5. Select Execute step.

The default Operation is Info, which returns instance information. Other operations: Delete, Get, Increment, Keys, List Length, Pop, Publish, Push.

To subscribe to channels, use Redis Trigger and set Channels.

For other buses, see [Publish with MQTT in Duaer](/build/mqtt.md) and [Publish with AMQP Sender in Duaer](/build/amqp.md).
