What are the limitations of Redis clustering?

Redis clustering has several limitations, including data sharding complexity, limited support for certain commands, and potential for increased latency.

Can you explain the data sharding complexity?

Sure! In Redis clustering, data is divided into slots, and each key is assigned to a specific slot. This can complicate data management and require careful planning.

What commands are not supported in Redis clustering?

Some commands, like certain Lua scripts and transactions, may not work as expected in a clustered environment due to the distributed nature of the data.

How does clustering affect latency?

Clustering can introduce additional latency due to the need for inter-node communication, especially during operations that require data from multiple nodes.
