# Buffer Pool Manager

## Overview

This project implements a **Buffer Pool Manager** with **LRU-K page replacement** and a **Disk Scheduler** in Java. It manages memory pages, handles concurrency, and efficiently schedules disk I/O operations.

## High Level Design

![bpm drawio_815644c9](https://github.com/user-attachments/assets/fb9de0bd-8622-4788-aca5-0e68ef4c99dd)

## Features

- **Buffer Pool Manager**: Manages fixed-size memory frames, acts as in-memory cache for read/write operations from disk.

- **LRU-K Replacement Policy**: Tracks the *K*-th most recent accesses for eviction decisions.

- **Disk Manager**: Handles reading and writing pages to the disk.

- **Disk Scheduler**: Manages I/O operations in a background worker thread.

## Installation

```sh

git clone https://github.com/yourusername/buffer-pool-manager.git
