Describe the feature

Implement In-Memory Caching for Faster Reads

Description
Currently, the cache system reads from disk every time a request is made. This can be slow, especially for large directories. Implementing an in-memory cache would significantly improve performance by storing frequently accessed data in RAM.

Problem

• Every request requires reading from the cache file, causing I/O overhead.
• Large cache files slow down retrieval times.
• No mechanism exists for quick lookups of previously fetched data.

Proposed Solution

• Use lazy_static and HashMap<String, Vec<PathBuf>> to store recently accessed cache data in memory.
• When fetching cache data:
  1. Check if the data exists in memory.
  2. If not, read from disk, store it in memory, and return the result.
  3. If yes, return directly from memory for a faster response.

Expected Benefits

• Reduces disk reads for frequently accessed cache files
• Improves performance for repeated requests
• Makes cache retrieval instantaneous after the first load

Record

• I agree to follow this project's Code of Conduct
• I want to work on this issue

@Pranav0-0Aggarwal, Along with this, I have created two additional issues related to cache and memory optimization. I have already worked out solutions for all of them and would love the opportunity to implement these improvements.

These optimizations will significantly enhance performance, reduce disk I/O overhead, and improve the overall efficiency of the caching system. Let me know if I can proceed with these!

Looking forward to your approval.
