HA KeyDB (Redis drop-in replacement)

• We will be using KeyDB (https://keydb.dev/) as our upstream Redis

  • KeyDB supports Active Replication (https://docs.keydb.dev/docs/active-rep)

Topology

• 2x KeyDB (Redis) pods (with Active Replication)
• 3x TCPProxy pods

The KeyDBs will be connected between each other using Active Replication and the TCPProxies will be used to load balance the traffic between the KeyDBs.

Deploying the example

• Deploy the KeyDBs using the following command:

cd examples/kubernetes
kubectl apply -f keydb/*

• Deploy the TCPProxies using the following command:

cd examples/kubernetes
kubectl apply -f tcp-proxy/*

Connecting to HA KeyDB

• To connect to the HA KeyDB, you have to connect to the TCPProxy service and port 6379

That's it!

You now have a HA KeyDB setup with Active Replication and TCPProxy load balancing.
