Memory Cache

A memory cache is a straightforward storage paradigm. One suitable example of a memory cache is a dictionary, where values are stored and retrieved using a key.

Distinct from a dictionary, the data in a memory cache can go stale based on a specified time to live (TTL) duration.
Additionally, it has a maximum capacity. Once the cache's capacity reaches its limit, the least-recently-used key-value pair is removed and replaced with the incoming value.

This particular cache should be able to hold a maximum of 100 entries, with a TTL of 60 seconds.
It is important to note that both the key and the value are always strings.


  1. Enable the TTL and maximum size to be read from a configuration file. Make sure to handle scenarios where the configuration file is not present or contains negative TTL or size limits.
  2. Additionally, allow the value type to be specified through the configuration file. This includes options such as int, double, or MyAwesomeType. The cache should accommodate both primitive and custom object types.
