Ledisdb
Ledisdb ist ein High-Performance-NoSQL-Datenbankserver, der in Go geschrieben wurde. Er fungiert als Key-Value-Store, der komplexe Datenstrukturen unterstützt und persistenten Festplattenspeicher nutzt, um Datenvolumina zu verwalten, die die Kapazität des Arbeitsspeichers übersteigen.
Das System ist sowohl als eigenständiger Server als auch als einbettbare Engine-Bibliothek konzipiert, die direkt in Go-Binaries integriert wird. Es verfügt über einen skriptfähigen Datenspeicher, der serverseitige Lua-Skripte für atomare Operationen ausführt, und bietet eine HTTP-API für den Datenaustausch mittels JSON-, BSON- und msgpack-Serialisierung.
Die Datenbank umfasst Funktionen für verteilte Datenreplikation zwischen primären und Replica-Knoten, um Hochverfügbarkeit sicherzustellen. Zudem implementiert sie Time-to-Live-Expiration für die automatische Datenentfernung, Benutzerauthentifizierung für Request-Sicherheit und Wartungstools zur Reparatur beschädigter Datendateien.
Features
- Complex Data Structure Stores - Implements a storage engine that natively supports complex types like sets and lists using persistent disk storage.
- Disk-Based NoSQL Databases - Provides a high-performance NoSQL key-value store that persists complex data structures to physical disk.
- Disk-Based Key-Value Storage - Provides a storage system that persists key-value data to physical disk to handle datasets larger than memory.
- Embeddable Databases - Ships as an embeddable engine library that integrates directly into Go binaries for local data management.
- Embedded Database Engines - Provides a database engine that can be integrated directly into a Go binary without external server infrastructure.
- Embedded Database Integrations - Integrates the data engine directly into Go applications as a dependency, removing the need for a separate server.
- HTTP Key-Value APIs - Provides an HTTP API for exchanging database records using various serialization formats.
- Persistent NoSQL Stores - Provides a high-performance NoSQL key-value store with persistent disk storage to bypass memory limits.
- Primary-Replica Replication - Implements a replication architecture where a primary node propagates writes to read-only replicas for high availability.
- Embedded Database Engines - Ships a database engine designed to be integrated directly into an application process as a Go library.
- Server-Side Script Executions - Runs Lua scripts directly on the server to execute complex operations as a single atomic step.
- Server-Side Scripting - Embeds a Lua virtual machine to execute server-side scripts for atomic operations and complex data logic.
- Key Expiration Management - Provides an API for setting and removing time-to-live values on keys to control automatic data eviction.
- Database HTTP APIs - Exposes a language-agnostic HTTP API for retrieving and modifying database records via JSON, BSON, and msgpack.
- Server-Side Scripting - Executes programmable logic such as Lua scripts directly on the database server for atomicity and performance.
- Embedded Lua Scripting - Integrates a Lua interpreter to provide programmable, atomic automation within the database server.
- Access Authentication - Implements credential-based restriction of access to stored data to secure database requests.
- Database Engines - High-performance NoSQL database based on LevelDB.
- Datenbanken - High-performance NoSQL database based on LevelDB.
- Embedded Databases - High-performance NoSQL database built on LevelDB.
