buffer-pool

A small but fast HTTP 1.1 and WebSocket server written from scratch in Rust using only the standard library. No third party dependencies.

DoraDB - Async Rust storage engine

Typed object pools for Go: generic sync.Pool, free lists that survive garbage collection, and buffer trimming policies.

UniConv - High-performance C++17 character encoding conversion library with SIMD acceleration (simdutf), O(1) LRU cache, tiered buffer pools, lock-free thread pool, and adaptive parallel processing. Supports 100+ encodings Zero-copy conversions & modern CMake integration.

Disk-backed B-tree key-value store in C++17 with LRU buffer pool and per-page POSIX rwlocks

The paging substrate beneath B-tree and heap storage engines - fixed-size pages, CRC32 headers with LSN slots, an LRU buffer pool with dirty-page pinning, and cross-platform Direct I/O.

Byte-buffer pool for Go: bytes.Buffer-like buffers that return to the pool on Close, and eviction of the oversized arrays a plain sync.Pool keeps reusing.

windows viper (for pentest)

Disk-backed key-value store built on extendible hashing, written from scratch in C++17, with a dbm-style CLI.

Go buffer pool with a target capacity: writes beyond it are slowed down gradually instead of refused, keeping memory use bounded without failing callers. Used by the unitdb storage engine.

C/POSIX ticket-booking demo with thread pools, seat locking, page storage, B+ tree indexes and WAL primitives. Socket-level concurrency/restart tests; crash recovery and undo remain incomplete.

A persistent, page-based B+ Tree storage engine in Go with a 4KB binary pager, LRU Buffer Pool, binary serialization, and interactive REPL.

Miniature Relational Database Engine with 4KB Slotted Pages, LRU-K Buffer Pool, B+ Tree, ARIES WAL Recovery, MVCC, and Volcano Query Execution

A single threaded database written in rust. Implements ARIES like WAL, table layer, network layer,buffer pool, B+ tree, paging and variable sized records.

Buffer-aware query scheduling for PostgreSQL 16: directional utility matrix + deterministic regret-sweep scheduler (extends Queryosity)

A lightweight relational database engine in Java with SQL parsing, 4 KB disk pages, an LRU buffer pool, persistent storage, and B+ tree indexing.

A learning project: an embedded, serverless NoSQL storage engine written in C11. Inspired by SQLite's single-file, in-process design — but for document/key-value data instead of relational tables.

Relational database engine built from scratch in Python: slotted-page storage, disk-backed B+ trees, a cost-based optimizer, ARIES write-ahead recovery and MVCC. Differentially tested against SQLite.

A course about the foundations of database systems, focusing on basics such as the relational algebra and data model, schema normalization, query optimization, transactions, and other more advanced topics.
