Many endpoints in Consul support a feature known as "blocking queries". A
blocking query is used to wait for a potential change using long polling.

Blocking Queries

Some read endpoints support agent caching. They are clearly marked in the
documentation.

Agent Caching

Most of the read query endpoints support multiple levels of consistency. Since no policy will suit all clients' needs, these consistency modes allow the user to have the ultimate say in how to balance the trade-offs inherent in a distributed system.

Consistency Modes
