What is PerfCache?

PerfCache

PerfCache is a neat little API designed for creating and managing memory caches. It's super handy when you want to speed things up by storing frequently used data.

Basic Features of PerfCache

This tool comes with essential cache operations like inserting and retrieving data. It even has some cool features such as replacement policies and expiration settings, which help keep your cache tidy.

How Does It Work?

The keys for cache entries are strings made up of bytes, while the actual data items are arrays of bytes. What's great is that you can use variable lengths for both keys and data. The whole cache system runs on an array, making it efficient!

Understanding Cache Infrastructure

The infrastructure behind the cache includes a directory that maps those byte string keys to specific indices in the cache array. Plus, there's a subsystem to manage metadata about replacing cache entries.

Replacement Policies

PerfCache supports two popular replacement policies: LRU (Least Recently Used) and LFU (Least Frequently Used). This means it knows how to handle what stays and what goes in your cache without much hassle. The management overhead for replacement metadata is O(1), which is pretty efficient!

Synchronization and Statistics

If you're worried about multiple processes messing with the same data, don't be! PerfCache has built-in support for synchronization. Plus, you can track how your cache operations are performing through statistics.
