This helps improve your cache hits, cache coherency and prevent cache stampede/thundering herd.</p> <p>Local cache means each server that&rsquo;s making the expensive query/operation, cannot be discovered by other servers. As a result, your cache hit as a whole is low. Distributed cache using external server like Redis improve the cache hit because when 1 server retrieve the data and cache it in Redis, other servers can re-use the same data.</p>
