Infrastructure to simplify client-side entity caching pattern

[hikalkan]

Consider the following scenario:

Order module (or microservice) queries a customer from the customer module (or microservice) and caches the result in the distributed cache. Then the customer module invalidates (simply removes) the cache item when the original customer changes.

The following figure shows it in a monolith modular application:

We typically write such a code in the order module:

This can be automated if we somehow enable client-side caching to dynamic/static client proxies and also application services with a simple attributed.

This is another typical code to invalidate the cached item:

We may also automate this with a simple configuration.
