Due to its client-server model, databases speed and performance are network-bound. Every operation requires round-trip communication over the network, which can significantly affect overall performance, especially in high-throughput systems or scenarios where network latency is a concern. One effective way to reduce this network overhead—and thereby improve application performance—is to implement client-side caching, also called near cache. This talk presents the concept of client-side caching, its benefits and tradeoffs, and how it can be implemented in a real-world scenario, using the Redis Java library Jedis.
