Rosedb

RoseDB ist eine eingebettete Key-Value-Datenbank und eine Log-strukturierte Storage-Engine. Sie fungiert als Bibliotheks-basierte Datenbank, die innerhalb eines Anwendungsprozesses läuft, um lokale Datenpersistenz ohne die Notwendigkeit eines separaten Datenbankservers bereitzustellen.

Das Projekt implementiert einen Bitcask-artigen Store und nutzt ein Append-only-Log-Format, um den Schreibdurchsatz zu maximieren und die Suchzeit zu minimieren. Es stellt Datenkonsistenz sicher, indem mehrere Lese- und Schreiboperationen in atomaren Einheiten gruppiert werden.

Die Speicherarchitektur basiert auf einem In-Memory-Key-Index für konstante Suchzeiten und verwendet Segment-basiertes Dateimanagement, um Datenkompression und die Wiederherstellung von Speicherplatz auf der Festplatte zu handhaben.

Features

Append-Only Log Stores - Implements a Bitcask-style store that persists data to an append-only file with an in-memory index.
Data Persistence and Storage - Provides durable storage of key-value pairs using an append-only log architecture.
Embedded Databases - Provides a lightweight database engine that runs directly within the application process.
Embedded Key-Value Stores - Provides an embedded key-value storage library that manages local data persistence in-process.
Offset Indexes - Maintains an in-memory hash map of keys to file offsets for constant-time value lookups.
Log-Structured Storage Engines - Implements a storage engine that treats the disk as a sequential log to maximize write throughput.
Batch Data Operations - Provides capabilities for performing bulk read and write operations as single atomic units.
Database Atomic Batches - Groups multiple database mutations into single atomic operations to ensure data consistency.
Log Segmentation - Divides the data log into smaller files to simplify compaction and improve disk space recovery.
Log-Structured Merge-Trees - Uses a log-structured merge architecture to organize updates and perform periodic data compaction.
Database Engines - Embedded key-value database based on LSM and WAL.
Datenbanken - Embedded LSM+WAL key-value database.
Databases and Storage - An efficient key-value store based on the bitcask model.
Key-Value Stores - Fast embedded key-value database supporting multiple data types.

goleveldb is an embedded key-value storage database for Go. It provides local data persistence and indexing, allowing applications to store and retrieve information using unique keys without requiring a separate server. The database organizes data using a log-structured merge-tree and persistent indexing in lexicographical order. This structure supports efficient range scans and prefix-based searches. The system includes capabilities for atomic batch writes to ensure data consistency and avoid partial updates. Performance is managed through write-ahead logging, memory-based buffering, and bl

RoseDB is a persistent key-value database and log-structured storage engine. It functions as a lightweight storage system that utilizes a log-structured hash table and a Bitcask engine implementation to provide fast data retrieval and disk-backed persistence. The system operates as an atomic transaction engine, grouping multiple read and write operations into single units to maintain data consistency. It handles data through a key-value model that supports individual insertions, lookups, and deletions. The database provides capabilities for batch data processing and atomic updates. Additiona

BuntDB is an embedded key-value store for Go applications, providing in-memory storage with optional disk persistence. It structures data using a B-tree for ordered key-value access and an R-tree for spatial indexing, allowing both range scans and geometric intersection queries. Support for indexing on nested JSON document fields enables efficient lookups by values within JSON objects, and per-key time-to-live (TTL) expiration automatically removes stale entries. The store uses copy-on-write transaction isolation, ensuring each transaction sees a consistent snapshot and changes are applied at

Pebble is an embedded key-value storage engine written in Go, designed as a library that provides durable, write-optimized data persistence directly within applications. It organizes data using a log-structured merge-tree (LSM-tree) structure, where writes are first buffered in an in-memory skiplist memtable and persisted to a write-ahead log before being flushed to block-based SSTable files on disk. The engine supports atomic batch commits, configurable write synchronization, and automatic background compaction that merges and rewrites sorted runs to reclaim space and maintain read performanc
