Reading data from slave nodes in Redis is crucial for building scalable applications to offload read operations, enhance performance, and ensure high availability.
Redis follows a master-slave architecture where the master node handles write operations, while slave nodes replicate data from the master to handle read requests, improving load balancing and redundancy.
Using slave nodes in Redis offers benefits such as improved read performance, high availability in case of master failure, and data redundancy for safety against data loss.
To read data from Redis slave nodes using Java, you need to set up a Redis server with master and slave nodes, use the Jedis library, and create a Jedis instance to connect to the slave node and fetch data efficiently.
