Redis Cluster Manager FAQs

Question 1

Can this skill automate Redis resharding?

Accepted Answer

Yes, it provides both interactive and scripted commands for moving hash slots between nodes, including safety checks to require backups before starting the resharding process.

Question 2

How many nodes are needed for a production Redis Cluster?

Accepted Answer

A minimum of 6 nodes is required for a production-grade cluster: 3 master nodes to handle sharding and 3 replica nodes (one per master) to ensure high availability and failover capability.

Question 3

What does a CLUSTERDOWN state indicate?

Accepted Answer

A CLUSTERDOWN error means the cluster is currently unavailable, typically because one or more of the 16,384 hash slots are not covered by an active master node or the cluster has lost its quorum.

Question 4

What is a Redis Cluster hash tag?

Accepted Answer

Hash tags allow you to ensure specific keys are mapped to the same hash slot by wrapping part of the key in curly braces (e.g., {user:123}:profile). This enables multi-key operations that would otherwise fail across different nodes.

Question 5

How does the skill handle Redis MOVED and ASK redirects?

Accepted Answer

The skill provides patterns for cluster-aware clients to automatically follow redirects, and includes troubleshooting steps for resolving redirect loops by refreshing the client's topology map.
