What is Redis clustering and how does data replication work?

Redis clustering is a way to distribute data across multiple Redis nodes, allowing for horizontal scaling. Data replication in Redis ensures that each node has a copy of the data for redundancy and high availability.

How does Redis handle data consistency in a cluster?

Redis uses a master-slave replication model where the master node handles writes and the slave nodes replicate the data. This helps maintain consistency, but there can be eventual consistency issues during network partitions.

What are the benefits of using Redis clustering?

The benefits include improved performance through load balancing, increased data availability, and the ability to scale horizontally by adding more nodes.

Can I use Redis clustering for real-time analytics?

Yes, Redis clustering is suitable for real-time analytics due to its high-speed data access and ability to handle large volumes of data efficiently.

What are some common pitfalls when setting up Redis clustering?

Common pitfalls include improper configuration, not monitoring cluster health, and underestimating the complexity of managing a distributed system.
