Are messages cached?
And chat apps especially, any recent message is going to be accessed a lot and anything written a day or more ago will be seen infrequently at best. The frequently accessed stuff can be cached according to expected use to get big benefits on performance.
What is caching in application?
Memory caching (often simply referred to as caching) is a technique in which computer applications temporarily store data in a computer’s main memory (i.e., random access memory, or RAM) to enable fast retrievals of that data. The RAM that is used for the temporary storage is known as the cache.
What is caching and where is it used?
A cache’s primary purpose is to increase data retrieval performance by reducing the need to access the underlying slower storage layer. Trading off capacity for speed, a cache typically stores a subset of data transiently, in contrast to databases whose data is usually complete and durable.
How does messaging apps work?
WhatsApp uses Extensible Messaging and Presence Protocol (XMPP) to exchange data between the users. The protocol is decentralized, secure, and flexible.

What is the purpose of caching in computing?
What is Caching? In computing, a cache is a high-speed data storage layer which stores a subset of data, typically transient in nature, so that future requests for that data are served up faster than is possible by accessing the data’s primary storage location. Caching allows you to efficiently reuse previously retrieved or computed data.
How to set caching in a function app?

What are the different types of caching layers?
