Code Structure

main.rs

The entry point of the application. It handles command-line arguments, initializes logging, sets up the server, and listens for incoming TCP connections.

db_manager.rs

Contains the RocksDBManager struct, which encapsulates the functionality for interacting with the RocksDB instance. It provides methods for performing CRUD operations, batch operations, transaction management, backup and restore, and more.

server.rs

Defines the RocksDBServer struct, which manages the server's state and handles client requests. It includes methods for processing different types of requests (e.g., put, get, delete, merge) and responding to clients.

helpers.rs

Provides utility functions and types, such as logging levels and lock file management.

cache.rs

The cache module provides in-memory caching capabilities to improve read performance and reduce the load on RocksDB. It includes logic for managing cache entries, performing cleanup, and synchronizing with the database.

queue.rs

The queue module implements a task queue for handling asynchronous write operations to RocksDB. This ensures that write operations are performed in a non-blocking manner, improving the overall performance of the server.
