Abstract
Systems and methods for domain name system (DNS) caching in a distributed processing engine include a first processing engine which may receive a DNS request for accessing a domain from a client. The first processing engine may generate a DNS query for a DNS controller based on the DNS request, The first processing engine may receive a DNS record corresponding to the domain from the DNS controller. The first processing engine may store data corresponding to the DNS record in cache of the first processing engine. The first processing engine may transmit a message including data corresponding to the DNS record for the domain to a second processing engine, to cause the second processing engine to store data corresponding to the DNS record in cache of the second processing engine.
