What is data consistency in Redis?

Data consistency in Redis refers to the accuracy and reliability of data stored in Redis, ensuring that all clients see the same data at the same time.

How does Redis handle data consistency during replication?

Redis uses a master-slave replication model where the master node handles all writes, and the slaves replicate the data. This can lead to eventual consistency.

What are the different consistency models supported by Redis?

Redis primarily supports eventual consistency, but you can implement strong consistency using transactions and Lua scripts.

Can you explain the concept of eventual consistency?

Eventual consistency means that, given enough time, all updates will propagate through the system, and all nodes will converge to the same state.

What are some best practices for ensuring data consistency in Redis?

Best practices include using transactions for critical operations, monitoring replication lag, and implementing proper error handling.
