Overview

A database buffer pool manager is a component within a database management system responsible for efficiently managing the storage of data in memory. It caches frequently accessed database pages in a buffer pool, reducing the need to repeatedly fetch data from disk, thereby improving overall system performance by minimizing disk I/O operations.

This repo is my implementation of a database buffer pool manager

Features

Buffer Management: Manages a pool of buffers in memory for storage and retrieval of data pages.
Page Fetching: Supports fetching pages from disk into the buffer pool.
Page Pinning and Unpinning: Implements pinning and unpinning of pages, allowing control over buffer pool pages that should remain in memory.
Dirty Page Management: Tracks and flushes dirty pages (modified pages) back to disk, ensuring data integrity and persistence.
FIFO Replacer: Utilizes a simple FIFO replacer algorithm for page replacement.

To-Do

• FIFO Replacer
• Rewrite in Go (cause why not)
