Possibility of generating cache

[avelino]

In some applications (or endpoint, depends on the use) cache is required to not be accessing the database (PostgreSQL) in every request.

by default it should be a key-value bank embedded inside prestd (no external dependencies) and support other external key-value banks with adapter architecture

Store key/value:

• key: endpoint + query string (GET)
• value: return body

configuration (TOML/ENV):

[cache]
time = 10M
store = bolt
sotrePath = "./"

sotrePath: native memory storage support (no path declaration required, :memory:)

Stores (adapters):

• buntdb - we are not thinking about performance, but it should be faster than running a query in postgresql, (bolt deprecated)
• badger
• redis
• memcached

Times:

• S or s: second
• M or m: minute
• H or h: hour
• D or d: day

If there is no cache in the configuration register (access the Bank in real time).

There is anybody working on this?

I'm just worried with invalidation mechanism. Query heavy update datasets can lead us to wrong results using just a timeout.
